I KNOW IT IS NOWHERE NEAR HALLOWEEN BUT
http://www.fileplanet.com/113998/110000/fileinfo/Swiss-Cheese-Halloween-Mod (and there are many other places that offer this fun mod, but I figured fileplanet is the crappiest one.)
The mod name, if you read, is called swiss cheese halloween. Bear in mind it has nothing to do with cheese. No. This mod uses everyone's favorite spirit coding for half life. And you get to enjoy seeing new weapons (albeit only one.)
The object of this game is, I kid you not, to escape from your boring, mundane life in a boring, mundane cookie-cutter neighborhood and enjoy a tropical island retreat with the girl of your dreams. (This mod assumes you like girls whatever gender you are.)
And so, this Halloween night, you try to express your discontent for normal life by going into that boarded up house in the corner of the street, of which rumours of an unspeakable horror resides. You ignore said rumours and venture into that house.
AND LO AND BEHOLD: GRIM REAPERS appear all over town and reap the neighborhood adults who are all out trick or treating (children are all in school.) You get on your trusty skateboard only to realize that a Random Giant Portal has sucked you to a Whole New Location. Well, you wanted to escape from boring life, and now you get to do just that.
IN TRYING TO CONVINCE YOU TO PLAY THIS EXCELLENT MOD, I will tell you all about this mod's merits. There are WHOLE NEW ENEMIES, including Witches, Ghosts, Aliens, Acid-spitting Aliens, Banshees and Scarecrows who drop MP5 when killed, Demons who drop AR grenades when killed, pumpkins that fire pumkin missiles, Giant Momma Pumpkin, and MUCH MORE! In addition to new enemies there are WHOLE NEW LOCATIONS TO CONQUER: a Pumpkin Patch, an old castle, A hedge maze, a swampy maze, a UFO, a witches Home, and everyone's favorite location, Hell, where textures are scaled up because in Hell, r_speeds are important. My
favorite part is where you ride an old Boat in a river for about 20 minutes on the way to Hell. Now That is Hell.
Clearly, this full-blown mod should rank HIGH UP THERE on the list of BEST MODS. You know. And if you want MORE OF THIS KIND OF WORK, Be sure to pick up the Half-life 2 mod of the same name! I don't play HL2 so I don't know if it actually exists or where the link is. BUT THE FACT REMAINS that I am Recommending This Mod To U and that you should try it out (instead of playing with bots on Steam you know.)
It's hard as shit.
