so far i made 3 games and i'd like you to try:
http://gmshow.gm-school.com/index.php?c ... the%20Dead < Doom 2D (Version i made. sucky AI but really fun! + cheats!)
http://www.freewebs.com/skdoom/index.htm < Doom Gates Of Hell. Doom in Golden Axe style!
http://gmuploader.uni.cc/main/download_ ... p?uid=1477 < Doom 2D 2 players COOp with the Strife Guy

Now i'm working on "Doom: Revolt Time!" Which is RTS like RedAlert. I'll be happy to ear some feedback...
