Description taken from PC version of this game

Final Doom is a stand-alone Doom II clone that features two new 32-level episodes: Evilution and The Plutonia Experiment. Blast your way through the 3D environment in yet another attempt to save the galaxy. Gameplay is the standard "find the weapons (chainsaw to BFG), find the power-ups (including the ever useful berserk and invulnerability), kill the aliens and get the keys to advance to the next level." All the evil demons of Doom II are back including fearsome foes like the rapid-fire missile spewing Revenant, the fireball blasting Mancubus, and the tougher-than-nails Cyberdemon. Two-player options include cooperative and deathmatch modes. ~ Joseph Scoleri III, All Game Guide
