Doom is a 1993 sci-fi horror first-person shooter developed originally by id Software for NeXTSTEP then later released to the public for MS-DOS. In addition to popularizing the FPS genre, it pioneered immersive 3D graphics, networked multiplayer gaming, and support for customized additions and modifications via packaged files in a data archive known as 'WADs' It was well received and has been ported to everything with a CPU in it, regardless of how ridiculous it sounds. (Doom on a printer?) This version for classic Macs was developed by Lion Entertainment in 1995.

In Doom, players assume the role of an unnamed space marine, who became popularly known as 'Doomguy', fighting his way through hordes of invading demons from Hell. You start off with a cheapy pistol and some brass knuckles, then along the way, you can pick up a shotgun thats more powerful, a chaingun that rapidfires your pistol ammo, a chainsaw to replace your brass knucks, a rocket launcher that explodes many enemies (but can also hurt you), a plasma rifle that shoots lasers, and a stupid powerful that can eradicate many enemies with only a few shots.

Wait, why does this need a description? It's doom! Everyone knows what doom's like! Even a cat in a hat.

Emulating this? It should run fine under: Basilisk II
