Project Osiris, Is a new Alien Breed 3D clone for ZDoom. Alien Breed 3D was a valiant attempt at basically creating Doom but for the Amiga. The game was a big succes on the Amiga platform but required a powerfull system for good gameplay. The new release for ZDoom includes all 16 maps and 5 weapons from the original game. The mod offers new redrawn graphics and visual effects and looks like the real thing. If you loved this game then check this out!
