Englische Ausgabe: Doom has you assuming the role of a space marine out to save the galaxy and the world. A portal has been opened that is spawning forth all sorts of hideous demons and alien creatures -- and they're not happy. The PlayStation version of Doom is more of a collection rather than the actual game. It contains over 50 levels of shoot 'em up action; the full version of Doom II and Ultimate Doom (the original Doom plus some "master" levels) included. Purists can rest knowing that every secret, room and texture has remained intact from the PC versions, though there are some modifications.
