Final Doom box-art

Final Doom was released in 1996, and runs on the same engine as Doom 2. It carries all of the same weapons, items, and enemies from Doom 2, and in the process, acts as more of an expansion than true sequel. It consists of 32 megawad files, Plutonia Experiment (by the Casali Brothers), and TNT: Evilution (by TeamTNT).
