I just played BOOM, that so-called "greatest modification ever made" and "fail troll mod" over at moddb. It is made by Russians.
If you go over to their moddb page, you can see how much the moddb community is in an uproar over this mod. Alot of people have banded together to form an anti boom club even, and about 70-80% of the mod comments are negative in some way. After playing this mod (taking me way longer than I wanted because theres NO DAM AUTOSAVES), I have concluded that though the mod is of sub-par quality, I have definitely seen worse maps than these, and I find some areas very boldly crafted (not necessarily player-friendly.)
First let's discuss the new models to get those out of the way. I'll talk about mapping later. So, the models, there's a few, and most are very bad reskins done with MS Paint. Just looking at their banner at moddb and you can see what I mean by this. There's some combine soldiers, but they're the buggy models used in ag3nt-x's invasion 105, so that was kinda annoying. The alien slaves, though pretty cool looking, are semi-broken. They cannot do their charge lightning attacks. That's right, all alien slaves will attempt to melee you on sight. Pathetic.
This mod features another problem never before seen by me in half-life modding history: the re-painted headcrabs and zombies have very long idle sounds, which I guess crowds up the sound channels, so that if I ask barney to follow me, he just says "yeah" (or nothing at all). Okay.
Gameplay is very, very imbalanced. In the beginning and middle, expect to be spoon fed with ammo and health and even batteries. Expect the gluon gun and ammo given before every garg encounter. Unfortunately, your favorite weapons like crossbow and rpg, those will not be provided (assuming I didn't miss them or anything. I couldn't have, because the maps have not much possibility for exploring.)
Which brings us to the mapping. Those Boom haters over at moddb have said that the mapping sucks. Well I can't wholly disagree. A majority of the maps are very repetitive. For example in the first map you make your way through a room featuring a wall medkit, wall suitcharger, some breakable stack boxes, and two zombies. Then you go through 5-6 incarnations of that same room. Very reptitive. And sad thing is, this will happen in almost every map except maybe the last 2-3 maps.
Glitches abound in this mod. Some of the level transitions are broken. Quicksave and quickload fixes that lil' mishap. Expect to see many, many fireflies. All of the level transitions bring over monsters from the previous map, so expect some weird things to happen like floating sentry guns.
Like I said from the top, the mappers were nooby, but very bold in their mapping. I didn't think first time mappers could strive to release a full-blown mod while still on the bottom of the learning curve, but these guys are the shiz. Most of us would prolly never be able to release a 10-map mod what with our overburdened schedules. I envy these people.
If you play this, you skills as a mapper will be insulted, but if you have an open mind and no life then go try this mod. Just remember, no autosaves. And the mappers didn't feel like giving you a good ending, so you will be executed by firing squad. And everyone else lived happily ever after.
Jk.
If they made a crappy mod that's their problem, leave them be!
They're no better than Checkerboard Studios, the guys behind the intentionally broken source mod, Checkerboard Hopes 2 and the very very controversial School Shooter, an apparent school massacre simulator based on true events.
