Oh yes. I gladly agree. Use featureful.

To get an idea what this SDK is capable of play mods such as
Field Intensity: https://www.moddb.com/mods/field-intensity
&
The big boned and the curious: https://www.moddb.com/mods/the-big-boned-and-the-curious

I'm mapping for Half-Life since 2015 and let me tell you that this SDK provides everything I always dreamed of when it comes to Opposing Force and beyond. It combines Spirit of Half-Life features, Sven Coop features and all of Op4 while adding tons of additional extras. That SDK for instance allowed me for the 1st time ever to get a true model replacement going by adding female scientists to the game including female death sounds. Even Spirit wasn't capable of that.

That being said - It's still getting actively supported. You need help - you ask the dev. You need a feature implemented - you ask the dev and if he finds it to be a worthy request he will implement the feature request to his SDK. I personally believe that for any none coder Featureful SDK will become the future default hl1 mapping SDK.

More Info: https://twhl.info/thread/view/20500

Where's the dl link to the beta hornet ?

May I recommend to use featureful SDK instead. It uses plenty of the SOHL features but adds all Opposing Force stuff on top including new mapping possibilities to make our lives as mappers easier and it even brings new coded monsters to the table.

Neat. I never considered to do it like this. Always thinking to complex at my end. Simple and swift work.

Check whether you're really compiling the map into the right mod folder. Check whether your Level Editor is really launching the correct mod folder. It always is the reason why these things happen. You may have checked a 100 times but eventually it comes down to a small typo like an accidentally added space-bar for example.

Load your mod manually and launch the map manually. Go check inside your maps folder whether your map is present in it and also check when the file was last modified. If you just compiled the map but the last modification was like 3 hours ago then you know that your map isn't either
A. compiling properly
B. Landing somewhere else

Ah you solved it, wonderful.

Func_Details shouldn't be causing this. I can't imagine that this is/was the true cause behind your problems.

Good job. I'm glad you figured it out. At present judging by the video the drone is still somewhat slower than in other importations that make use of it.

Glad to see you still around Awkook.

@SirCobalt. Best you join Discord to get realtime help and an exchange of knowledge.

Ok, sounds good.. Make absolutely sure to join the Discord Server. There you will receive help almost in real time. Although lesser help than it would be the case, say for mapping. There are obviously lesser coders around in the hl community than mappers.

Hey
I'm not a coder myself but tell me ? Is your goal to create something entirely new. A npc that's totally different than anything else we know from Hl1 and Opposing Force? If that answer is yes. Then you must wait till somebody who can code helps you out.

If the answer is no and you just wanted new skins or additional body groups for your models then I suggest to you to use

Featureful SDK:

It's primarily made for people that can't code themselves. That being said it already contains all Opposing Force Monsters such as Pit Drones, Voltigores, shock troopers, functioning Ropes, model and sound replacements (including npc death sounds) and so many more amazing features. Tomorrow a new update is scheduled to get released. So it's actively maintained and the author tries to implement feature requests made by us the users.

Unified SDK

If your desire is learning how to code yourself then I suggest you use Unified SDK instead. It has 1000 of Engine bug fixes, new features for script and audio usage and is by far the most advanced & stable- bug fixed SDK out there. That SDK requires you to be able to code yourself and having intermediate knowledge.

Thanks for letting me know about that. I just tinkered around with your various config files and also read your github guide. This project is truly stunning. I've finally switched from Fi 1.6 to featureful.

Still missing all the fancy Field Intensity monsters though, but all in the good time, eh?

The fact that you won't re-add your story, thought and radio features saddens me immensely. Besides your mod and Todesangst2, Point of View I can't recall any other SP mod that ever did something similar. Would be a massive boost to any story driven mod to get that included in featureful even if it was just experimental.
Any chance on getting the Squad disband and recruitment feature into Featureful? Might be useful for all sorts of Npcs later on.

Bug report: monster_flyer_flock won't accept my custom models. It launches by default with the Boid model. But what I'd like for my XEN map is the real flock.mdl model. The model animations are present and accounted for.

So far I'm very happy and very grateful to you and your ambitious project..
For you: http://sndup.net/t8hd

Sounds lovely... I will have a check on it. At the moment I'm working only with your Field Intensity Build v1.6 so I haven't even started yet to check out featureful.

Are there some documentation files you published somewhere explaining what each new entitiy does? I did go through your test maps on the Field Intensity SDK. Some maps didn't work as they should've as far as I could've determined.

Anyway stay on it. You're doing a wonderful job as always.

I love you guys for doing this. Your todo list also looks very impressive. It will contain everything I always dreamed of.

Additional wishes or recommendations if not added yet:

-Solokillers random trigger spawning possibility. Making each play through unique and different.
-Solokillers triggers that only activate based upon the set difficulty.
-Solokillers Audio library & entity maximum extension. (I believe that was already included within Field Intensity, am I right?) So that the game allows for more maximum npc sentences written within the sentences.txt and an increased number of entity usage within any given map.
-Fix on Field Intensity Code and probably here as well to give Hecu_Ally_Grunts a rifle. When I spawned em per entity or per console they still spawn without a rifle just like in the original Op4 SDK.

As far as Monsters go possibly this:

-Hecu Minigunner, seeing how you're gonna add the minigun at some point.
-rpg hecu and blackop rpg variant- also being able to take on choppers.
-Robo Grunt of the censored German Version?
-Decay: npc Keller. Rosenberg is already in it if I remember correctly.
-Eventually a port of the Sweet Half-Life Hev Suit npcs & the Grey Aliens?
-Would be cool to get the Todesangst 2 Loader Enemies in as well. That was a one timer. Haven't seen anything like it any other Half-Life mod since.
-Eventually female Scientists https://gamebanana.com/mods/393927 (I've got a full sound set ready, based upon their male counterparts.)
But it's not yet released. Let me know if you're interested in obtaining that.
-Female Azure Sheep Security Guards.
While these can get added in by the mapper themselves it might save time and would serve as full package for any upcoming mappers to have everything available from start.

Last but not least a minor and more fun like request:
-If permission given add the brown shocktrooper variant of this SDK project onto your project: https://www.moddb.com/mods/opposing-force-enlightened It uses the former Alpha model but enhanced to the default op4 standards and uses the spore launcher instead the shock roach. Of course it's just a simple weapon and model swap within the entities in the editor but still kinda cool to have. Maybe eventually as 2nd skin within the model itself? Might be even cool to have for Field Intensity. That combined with a slight different pitch within the monster entities and you get a female version of said Alien.

---

As far as the Archer is concerned: I love how it got handled back in Azure Sheep, game play wise.
Although an additional distance attack might not be wrong especially if the player is hiding behind something in the water.

It could have 3 attacks.
1. When it comes under close range attack from the player with a crowbar it will release a minor electrical charge which stuns the player and their vision, swims off before charging or long range attacking the player again. Similar like you did with the Alien Slaves.
2. the regular bite animation that azure sheep portrayed
3. and your suggested pit drone like attack.

I'd love to get the sounds from the Azure Sheep version for it. It had the best sounds for the Archer and the most memorable.

Stukabat - Hl: Point of View - hanging as ammo or idling around in the air and attacking any humans once it sees them.
Panthereye - Hl: Invasion, yes.
Charger - Hl: Invasion, yes.
Alienflyer aka Aflock - Love to see a dynamic flight script like you did for the boid.
chumtoad - Idle walking and hopping logic like for the boids. If approached to closely they explode on you.

This is related to the custom game code you're using. The sparks appear whenever the npc begins an action. Usually when the npc starts speaking.
It is - it was for testing purposes of the coder to see whether their modifications made to the code were working and the npcs starting to speak as intended.

Unless you can code yourself or at the very least read lines of code you could remove that particular line which spawns the sparks over npc heads yourself and then recompile the code. If you can not so ask around perhaps one of the coders browsing on this site might be willing to help you out on this one. For them it should be a mere matter of minutes to find the specific line, delete or exclude the line and recompile it.

The code you're using is still being actively worked on so keep that in mind.

Would be cool if you could re-add the lovely old Animation Clip of the Op4 WON version where we've seen Ospreys and soldiers running around. While it serves no purpose it might be fantastic for nostalgic reasons. Naturally something like that has 0 priority but eventually at very end as final touch.

Your current progress looks brilliant.

If you have many leaks in your map. The box method is the best way to quickly discover leaks. Just place a solid cube over most of your maps and work your way through it by adjusting it's size till no leaks remain. Rest assured it's a pain in a butt going on a leak hunt.

You're welcome. I'm glad it worked out for you.

Well it's related to the model.

Bone02 that the model has is unknown in the QF. You either used the QF file of another unrelated model or you removed Bone02 in Milkshape which was originally part of your model and therefore listed in the QF file. Best you write or compile the QF file from scratch but I'm uncertain how I always just modified existing ones adding Animations to it nothing more.

It's also possible that Milkshape created this bone as starting Bone. Blender adds a pre defined bone structure as well. You would've to manually remove it in the Program. Why don't you take a look in Milkshape and search for bone02 and see if it's actually part of the model if not delete it.
Half-Life complains if there are bones in a model that are not defined in the QF and vise versa.

And seeing how you seem to be unaware of this great mod there you go:

https://www.moddb.com/mods/uss-darkstar

Personally, I in your shoes would release the SDK's for Hl1, BS, Op4 standalone in a version 1.0 where you add everything as was it was originally for their respected games just with the additions of your countless fixes and optimizations included. Then I'd focus solely on your unified SDK enhancing it and improving upon it till a version 3.0 or till you're absolutely satisfied with it yourself.
On a mappers perspective I would love to get some sort of repository containing everything that the community ever came up with in 1 huge package for the mappers to choose from and play around with in essence to create the ultimate mod and no I'm not talking about having 100 different weapons at your disposal.

Be it a Rosenberg Entity or some Grey Aliens from Sweet Half-Life (Assuming permission is given) maybe any cut Hl1 monsters with working AI etc. that and of course many of the useful features that Spirit first introduced to the mappers and that you yourself came up with. Be it simple fog or an "entity follows entity ability" which for example was shown and used in Point of View where fire and explosion entities followed the downing Osprey in the Op4 Intro Sequence Remake or model and sound swapping.

That combined with your texture size enhancements, your improved and enhanced general game play performance should be all a Hl1 mappers Heart desires. It's a bit saddening seeing how you couldn't improve upon the sentence.txt text size limitations but that was to be expected.

In regards of decompilers. That's how I actually learned to conduct my mapping or rather entity scripting. I became quite adapt at it thanks to the decompiler tools. In my case I rebuilt scripting wise a Test Chamber from the very map that won the Test Chamber Content award here on TWHL. In another map I rebuilt an entire corridor even replicated it's textures but added my own personal touches and visions into it. It helped me understanding how to properly carve brushes and how general brush work should look like in my early mapper days for Hl1. That said corridor was this one: https://media.moddb.com/images/mods/1/14/13305/Evac.jpg In the original (another Twhl content map) there used to be a Tram line down there. In my vision I added a cave instead with a helipad inside it. Nowadays I naturally built all my maps entirely on my own (Not counting donated maps). Still - I believe taking inspirations of other artists can never hurt 'cause that's what it usually is - Art. That's how humanity competes with each other and advances technologically. There's always somebody who thinks they can do things better than the predecessor.

Those who want to steal work of others always will find their way and they won't care either. So I don't think that it should be of any concern to any us. All you could do in the hopes of preventing it is to mention explicitly to respect the work of others by not taking their stuff. At the very least use it only with their proper consent and credits given as it always should be in such a case. Personally I feel that the Half-Life Community was always a rather respecting community when it comes to Single player content. Lets not talk about the MP branch 'cause that's a very different subject. Anyway in my opinion it would be just fine.

Both the Hl Community and Armed Assault Community in my personal experiences were both 2 of the best communities where people always helped each other so much that the end results often resulted in created content which even surpassed the quality of that of their original respected games. That's something to be very proud of as it is unique and also keeps any game alive (@All Companies: Make this Truth to your own. :D) So I'm in favor of an enhanced decompiler tool.

Hm few years ago I tried myself out on VirtualStudio. Trying to compile a modified engine code for hl1. I failed horribly and received countless compiler errors till I gave up on it. If CMake behaves similar or is even identical I'd prefer the easier method of having something behaving similar than Spirit of Half-Life something that largely pre configured. Something that allows the mapper to start mapping right away without having to worry to much about config files, project files. Merging and syncing files online even.

I suppose it all comes down to the general accessibility. Now I do realize that this won't be similar to Spirit at all but you know what I meant by drawing this comparison. That being said I prefer only official releases done by you and your fellow helping hands such as Shepard.

Glad that it worked out for you.

You may have accidentally created a new bone called bone09. But that is unlikely seeing how it is called bone09.
What exactly did you do while looking at the model in blender? Did you copy meshes and body parts of it into an own model of your making?
Make sure that if you did that. That you copy all attached bone names as well as the body meshes (or their groups) onto the new model mesh.

Keep in mind that you can not copy paste models (for example new torsos.) onto another models head without making adjustments to the bones which are all parents of specific mesh groups. Some models got like exp. 128 bones while others perhaps only got a 100 bones. You would need to de-parent all the meshes of it's old bone structure and parent the meshes onto their new bone groups from scratch or by selecting several parts of the meshes to the desired bone section.

Bones are actually that what makes the models move later on in any game. Like our bones inside our own bodies keep us from falling and collapsing in itself to the ground as 1 large bag of water. The very fabric of what we namely are - bags of water. I suggest you checkout some tutorials.

Check out the great tutorials made by Tetzu0:

Have fun.

They should work considering that I played numerous Opposing Force mappacks that featured both your allied grunts and regular grunts as enemies, allies of the Black Ops.

https://www.runthinkshootlive.com/of/

You must be fairly new to hl mapping.

monster_human_grunt is basically the counterpart to a regular Hgrunt entitiy. He can follow the player he can attack on his own.

His allies are: The player, other hecu grunts. That soldier is hostile to everyone else. Did you never play Opposing Force? No? Go play it now.

Make sure to place info_nodes in your map. These info_nodes are important for the npcs. They use these entities as waypoints where they will run to and take cover and so on. Without these info_nodes placed on your map your npcs will behave very poorly.

Something like that usually happens when you didn't map on the grid and or also when you carved objects numerous times making them thus very complex in shape or size. Same applies for mini brushes that exist out due carving brushes.

What you could try is to use the special textures on said brush.

http://zhlt.info/special-textures.html

I doubt it will work though. Best you recreate said areas. Also check whether there are overlapping brushes. That could also cause these errors.
Sometimes you may have accidentally created a func_door or any other entity on the brush which then results in the things shown in your screenshots. If there are indeed some entities used make sure to add a 2nd wall behind these entities in order to avoid looking into the void. Func Entities should never have an actual connection that extends outside the actual map aka to the sky and void.

At least on the 2nd screenshot I'm almost certain that you created the wall as a block and then carved the ceiling wall down these 45 degrees. Don't ever do it like that. Place another wall onto of the current one. Extend it all the way down to where you need it so that it sits on the same coordinates as the bugged wall and then use vertex manipulation and combine it with the other vertices linking them together as 1. Once accomplished retexture the wall based upon the malfunctioning 1 and then hide the new wall. Afterwards delete the malfunctioning 1 and make your new wall visible again and test if that fixed it.

Remember: Never carve a square into several segments unless it's a clean cut going in 90 degree angles. Work with numerous brushes or triangle brushes instead.

You can swap Barneys Head if memory serves correct but not his body mesh due to the way the Engine handles it.

I'm afraid that you need a custom code in order to get it to work the way you intend.

Zombies on the other hand had no special sub models like pistols and such things attached to their model which is why body model swapping works on them.

Hi Solo I'm trying to switch from Jed's Half-Life Model viewer to your superior Asset Manager.

Could you explain to me how to properly set up your tool?
I'm struggling to compile models with your tool.

What .exe in program path do you expect me to link there? That of Half-Life1 ?
Could you tell me a bit of the proper default features that should be enabled/disabled when compiling for an intended use in Gold Source?

Thank you in advance.

Hi guys it's been many years since the release of my female Scientists.
https://www.moddb.com/games/half-life/addons/female-scientists

Today I am attempting to rig a head onto a main body mesh but I can't recall how. It's been to long. Could any of you tell me again how it was done.
I checked through the old tutorial vids of back then but the solution eludes me.

This is what I did:

Importing my HECU head deleting it's bones and then importing the HECU main body_mesh. Now I can't remember if I had to parent the head mesh to the main body mesh or if I had to parent both meshes to the bones but I'm also getting a No bone selected error.

If any of you could tell me in simple layman terms what I'm supposed to do in chronological order I'm certain my memory will return immediately. It's just my uncertainty to know which step to perform when at the moment. Thank you

EDIT: I solved it. I just had to replace the head mesh and add the new head instead and combine the remaining meshes with the new head.

Sounds wonderful as usual I wish you best of luck.

Congrats on the release of these fancy tools. They're indeed a huge improvement over the classic versions. Thank you Solokiller.
How's it going on your SDK Frontline? Hl1,Op4,BS ?

You don't create a weapon walking animation. The weapons are attachments attached to the primary model itself. There you control how they hold and control their rifles during any animation they play.

If you refer to a specific animation where the npc or player touches his gun it applies to the same principle.

Little more description would be appreciated. You want our help then invest some more time in writing us what it is you need help with.

Either way. So you capped some screenshots that you wanna see in game for placing on walls etc. is that it ya ?

Download wally

https://www.moddb.com/games/half-life/downloads/wally1

And add these screenshots into your own .wad file.

The files must be either in .bmp, .tga, or .jpg format and be dividable by 16 so 128x128 or 256x64 8bit color format aka 256 colors.

Ya you're right @Captain P coming to think about it.

8 bit equals 256 / 0 to 255 colors. 16 is also dividable by 2. But ya I should have said 16.
If memory serves me correct certain compiler can't read certain formats but in general you once more right. It's more the engine itself that can't handle this my mistake.

Heya there are possibly 3 reasons why your .Wad file won't work.

1.) Textures in Half-Life need to be in 256 bit colors.
2.) Textures should be dividable by 2. So for example: Your texture must be 256 x 256 in size. It can't be 255 x 255 'cause you can't divide that through 2.
3.) It is vital that textures are in .TGA Format although modern compilers such as this https://twhl.info/thread/view/17830 also allow .jpg Format but it is not recommended. That being said you get an increased quality loss with .jpg which can result in Artifacts getting displayed on your textures after the compile.

...Help request...

Hey folks:

I was wondering whether one of you coders out there could help me implementing some Spirit Features to Solokiller's amazing Op4 Code.
https://github.com/Solokiller/halflife-op4

So that I can finalize upon my merging of 'and between Military Duty & Firestorm.

https://www.moddb.com/mods/military-duty
https://www.moddb.com/mods/hl-opposing-force-firestorm

I won't go into any details but for a real coder it's probably a matter of mere minutes implementing some of the required features that Spirit provides. If you like to see Military Duty in a similar length to that of Opposing Force itself getting released I'd appreciate any help . Just PM me here on this very site if you're interested in lending a hand. I wish I had the mental capacity to figure this out myself but after the idk 15 attempt at figuring out the file structures and correlations between files I had to accept the fact that I'm simply put -- no coder.

Greetings 23-Down

I once attempted modding back in IDK 2002. But nothing ever came out of it. My English wasn't that great and there weren't enough tutorials that helped me back then. Eventually my English improved and I managed releasing Military Duty 13 years later.

Right now I got this abandoned Mod sitting on my HDD.

Firestorm

https://www.moddb.com/mods/hl-opposing-force-firestorm

I still got all the textures, models, sounds and RMF files related to that mod project. My plan was to eventually merge that mod with my released Military Duty mod to form this into an even larger & massive mod experience similar in length to that of Opposing Force itself. I wish somebody could compile me a Spirit v1.2 with all working Op4 entities included. But I never found a coder able to do so and sticking around till the end. I attempted to incorporate entities such as the Voltigore and the reverse engineered ropes by Solokiller myself many times already but I just won't get the hang of it. So in essence it kept me of merging the 2 mods thus far as I require some vital Spirit features in order to utilize several of my ideas. That makes it basically unlikely that we will ever see contents of Firestorm any time soon.

------------------------------------------------------------------------------------

I remember "Welcome to Black Mesa" and I was a huge fan of your mod @Cabo Fiambre. In fact mods such as yours served me as inspiration in my very early mapper days. It's sad that you've never finished it.
Should you still own the mapping files you might consider uploading them open source, who knows some other mappers out there might still make good use of it. That way your work wouldn't have been in vain and others can enjoy it. I often wonder how many Gigabyte of Data regarding Half-Life maps and mods are still floating out there throughout the world - unreleased.

https://www.moddb.com/mods/welcome-to-black-mesa <<< There's even another mod with the same name than yours. But that's unrelated to your ancient mod or? Either way it's equally dead and never got released.

-------------------------------------------------------------------------------------

"Particle Fusion" is another mod that I follow closely @Supersonik. It most certainly looks stunning and I hope we will see it one day in the future don't let it die. Don't let any of your amazing mod projects die. Don't you dare.

Can you give us more information about what exactly this mod is about? I read some of the moddb reviews and they are indeed positive and highly rated yet the maps (based on the screens look basic at best). What exactly is the purpose of your mod? What does it do that normal HL1 doesn't do?

I know the guy.. He helped me with my own code till we both discovered Solokillers work. Then he ceased development. The public code is even less sophisticated than the private one I own and even that it a total dev build. For instance many NPC actions spawn a spark on top their heads for verification that things worked as intended coding wise. Unfortunately I'm to stupid and limited in time to figure things out myself.

If you got the coding know how let me know and I'll send you that internal code. He fixed dozens of spirit related bugs and cleaned up the whole code of it big time. At least so he claimed but I believe that he did.

They relate to the pitch and other sound effects of how said words will sound like. Best you browse through the tutorial section and other people their topics section on this very website before asking questions that are easy to answer yourself.

Black Mesa used to be an ICBM base (inter continental ballistic missile) during the Cold War. Long before they turned it into a research facility.
It stands to reason that the Military had a minor detachment stationed there before and during the Resonance Cascade.

As for the Helicopter. It's one of Americas finest attack helicopters. Enhanced and upgraded for many decades now. I'd type something relating to the specs and that our proud (their) military is continuing with help of Black Mesa's weapon and research division to enhance it even more. A bright star on the horizon regarding the future. Stuff like that.

https://half-life.fandom.com/wiki/Black_Mesa_Research_Facility

https://en.wikipedia.org/wiki/Boeing_AH-64_Apache

Be advised: That code was incomplete and only preliminary in it's release.

It is possible but requires some minor editing and conversion work.

https://steamcommunity.com/sharedfiles/filedetails/?id=276991683

Several mods I own got this implemented and it works without any actual doing on my part.

And in this particular case it would be the sentence name:

!NA

!NA0

for Access Denied!

Func_Trains are tough to get going. I struggled with it myself. What you need to do is to set a path corner for the route. Func_ Trains won't properly work on regular path entities. If memory recalls you need to mount a linked route for it by holding down crtl + left click and creating the whole route for it that way.

Perhaps someone else can shed some more light on it. If not give me a shout and I will create you an example map which you can copy and paste into your own map.

Wasn't labcoats required renamed into Scientists Adventure later on and that mod never came beyond a minor demo release?
I could be confusing things but the name does indeed ring a bell for me.

@Jackn0
Half-Shock was an unfinished mod project with no opponents in it as memory recalls. I did play that back in the days.
As for mods not working just copy your cl_dll and dlls folder of your Valve folder into the mod folder and the mod should work as intended. In many mods I got I often notice that I can't switch weapons 'cause the dlls are missing. If the intended mods still don't won't it might be due to missing wad. files. Should you get this error ED_Alloc: No free edicts. Then there's a command you can add in a shortcut for the main half-life.exe in the target line: -num_edicts 4095 -mod NameOfHLMod that fixes that error.

Hm sounds interesting.. Perhaps cap some screenshots of the files names in list format.
I myself am a collector. You might own some mods that I myself was looking for - for a long time, mods that are equally lost but not considered right now.

Note: Blackop Mission is still under development. Most likely what you owned was only a minor demo release.
I'm his beta tester and last I talked with him, idk like 6 months ago he said he was still working on it.

I still got Cleaner's Adventures Begin on my external HD. But guess what the Hard Drive is giving me a bad indexing error and has bad clusters as of today when I wanted to open my archives just for this topic here.. I hope I will be able to fix it considering I got plenty more archived things on it that would be lost for ever if I can't fix it.
Pretty sure I still got Panic at Black Mesa at that broken HD too.

Rest goes only as far as saying I might still have xyz burned on CD's.

Infinity
Xen Crystal
Secret Santa 2011 on broken HD
TWHL for the "Xen Trasportation"

While it's sad I don't think it's a huge loss here with few exceptions. Simply considering that most mentioned maps were merely created for various competitions which often just contained graphics but no actual game play.
I still got a CD with maps that aren't even known anymore to modern hl1 players as they vanished in the late 90s not long after Half-Life's actual release but even here stands to say that most maps were tiny like fighting against an Apache on a roof top with a mounted RPG and so on, so nothing special. I'd like to think that the community did an epic job in preserving up to 80% of the true Gems out there. 18% were junk and not worth saving and 2% like Gargantua Mod Chapter One were simply overlooked casualties.

Sounds good. I was wondering whether you're still working on your project.. Good luck to you.

Hey that looks brilliant @koe1...
