Doom 64

Doom 64 Dreamcast is a 2024 community port of Midway's 1997 Nintendo 64 first-person shooter, adapted for Sega's Dreamcast by jnmartin84. It is not an original commercial Dreamcast release: the underlying game was developed and published by Midway, with id Software overseeing the Doom series. The port brings Doom 64's distinct campaign, redesigned demon roster, weapons and unsettling audiovisual identity to Dreamcast hardware, giving the console an unofficial but purpose-built version of the game.

The single-player campaign returns a lone marine to the abandoned UAC installations after a surviving demonic force begins restoring the creatures defeated in the earlier Doom games. Progress follows the series' familiar, immediate loop: explore hostile bases and hellish spaces, find colored keys and switches, uncover routes through locked areas, manage health and ammunition, and reach each level's exit while surviving traps and ambushes. Its maze-like stages reward attention to changes in the environment, including rooms that shift or open as objectives are completed.

Doom 64 retains the essential Doom arsenal, from the basic pistol and shotgun to the chainsaw, plasma gun, rocket launcher and BFG 9000. It also features the Unmaker, an energy weapon whose power can be increased by locating hidden artifacts. Most returning demons have new artwork, while the Nightmare Imp and the final Mother Demon give this entry enemies of its own. The result is recognizably Doom in its fast weapon switching and close-range pressure, but its character designs, colored lighting and ominous soundscape set it apart from Doom and Doom II.

The original Doom 64 campaign contains a full set of main stages plus secret levels, built specifically for the Nintendo 64 rather than simply converting the earlier PC maps. The Dreamcast adaptation is based on reverse-engineered Doom 64 technology through Doom 64: Merciless Edition, preserving the game's native map format. It can also make use of the additional Lost Levels material associated with the 2020 Doom 64 re-release when the appropriate assets are supplied, extending the campaign beyond the original ending.

This Dreamcast version is a homebrew project rather than an official Midway or Sega product, and its development reflects the later preservation and technical interest surrounding Doom 64. Updates have added Dreamcast-specific enhancements such as dynamic lighting and bump mapping, along with mouse and keyboard support. For players interested in Doom 64 on Dreamcast, it offers the original game's solitary demon-hunting campaign in a version created for the console years after its commercial life ended.
