DOOM 2D (2001): id's Classic Reimagined as a 2D Side-Scrolling Shooter

Rating band: Fan-favorite · Year: 2001 · Developer/Publisher: Freeware release · Platform: DOS · Theme: Organized Forces, Unique

Take id Software’s most famous shooter, flatten the perspective to directly overhead, and keep everything else intact: the marines, the monsters, the textures pulled straight from the source material. That’s the pitch behind DOOM 2D, a fan-made freeware project that spent real effort recreating all 19 of DOOM’s original levels as a 2D side-scroller rather than settling for a loose homage. Anyone who’s spent enough hours navigating the 3D maps can, with some mental gymnastics, recognize familiar rooms and corridors once they’re flattened.

The faithfulness goes beyond level geometry. Weapons carry over with reasonable accuracy, and the two multiplayer modes on offer, cooperative and the classic deathmatch, mirror what made the original a fixture of LAN parties in the first place. What’s missing is polish in smaller places: sound effects are sparser than the source material, and the whole package occasionally runs into trouble under Windows, which is why running it in a pure DOS environment is the safer bet.

One detail worth knowing: DOOM 2D didn’t start in English. It was built and released in Russian first, with an English translation arriving afterward for players outside that market. That’s the version that circulates today, and it’s the one worth tracking down if the language barrier would otherwise be a dealbreaker.

There’s also a companion map editor from the same project, though by most accounts it’s not especially intuitive to use. It’s there for anyone who wants to build their own levels rather than replay the recreated DOOM maps, even if the learning curve is steeper than the main game’s.

Compared to some of the era’s stranger DOOM-adjacent oddities, including Textmode Quake, DOOM 2D reads as the more disciplined effort: a genuine attempt to translate a specific game into a different perspective rather than a novelty riff on the format. It doesn’t reinvent anything. It just executes a fairly ambitious fan project competently, with no glaring bugs and controls that take almost no time to learn.

How to run it today

DOOM 2D runs through DOSBox without much fuss, provided it’s launched in a pure DOS session rather than through a Windows shell, which is where the original release ran into conflicts. Mount the game folder, run the executable, and the controls behave the same as they did on period hardware.

Compatibility: DOS (via DOSBox, pure DOS mode) · Controls: Keyboard, DOOM-style movement and combat · Setup difficulty: Low

Legal status

DOOM 2D was released anonymously as freeware and draws directly on assets and level designs from id Software’s DOOM. There’s no publisher or studio credited on the project itself, and no indication that id Software has ever pursued or licensed it. Whether that silence reflects tolerance or simple lack of attention isn’t something that can be settled from the available record, so the honest answer is that the legal status sits in a genuine gray area rather than a clean one.
