Aye, Evil's work looks great, I hope he puts it out soon. On the note of Xeno's.... a Xeno Mod for the Invasion gametype would rock.... Blasting at hoards of aliens crawling out of every nook and crany with your friends, back to back.
Speaking of which, so far as I've seen, the AVP engine is the only one to ever full on let you walk/crawl on walls, ceilings and whatever else... I really wish they would release a new game, nothings more fun than hissing in the ear of some player online because he didn't notice you crawling down the wall behind him... *Chomp* Headshot.
The Doom 3 engine would be perfect, but its too damn laggy, even on a decent rig. =/
Annnnyyywhoo back on subject, I agree... the more the merrier. Bring on the Preds.
