Final Doom is a 1996 first-person shooter video game developed by TeamTNT and published by id Software for MS-DOS.

Both megawads were created by members of the hobbyist group TeamTNT, with id Software purchasing the rights to TNT: Evilution just before its planned free release[3] and The Plutonia Experiment being made specifically at the request of id Software by Dario and Milo Casali.

During August 2022, Final Doom was delisted from the Steam store, in an effort from id Software to consolidate their games' multiple releases and editions.

A few months later, the yearly supply ship comes ahead of schedule, and looks strange and unusually big on the radar.

The personnel of the base go out to behold the terrible truth: it is a spaceship from Hell, built out of steel, stone, flesh, bone and corruption.

After being attacked by an imp, he rushes back to the base where he sees the demonic spaceship still hovering above it and realizes what has happened.

The UAC is refounded under completely new management (the old trustees and stockholders were all dead anyway) and aims at developing tools that would prevent demonic invasions.

For one hour the Quantum Accelerators manage to close 6 of the Gates, but the Hellish army has become too numerous and too strong.

The original TNT: Evilution megawad was created by TeamTNT, a group of WAD-making hobbyists who were active on the 'advanced Doom editing' mailing list.

However, just 5 hours before its release John Romero contacted the leader of TeamTNT, Ty Halderman, with an offer to acquire and sell the project as an official product.

"[3] The 2-3 dozen core members of TeamTNT formed a legal entity and completed the sale to id Software a couple weeks later.

[10] Brothers Dario and Milo Casali, who had contributed eight levels to TNT: Evilution, were assigned the task of creating what became The Plutonia Experiment after having sent an eight-level WAD they had created to American McGee and managing to impress him along with the rest of the id Software crew.

Unlike their contributions to TNT: Evilution, which were edited by id Software before the final release,[c] no revisions were made to or requested for these 32 levels.

[14] While GamePro criticized that Final Doom has no new enemies or weapons, and that the PlayStation version includes only 30 levels as compared to the PC version's 64, they were pleased with the "huge, perplexing, and sometimes sadistic levels" and the new scenery, and considered Doom still a compelling enough game that simply more of the same was enough to satisfy.
