Freedoom – Doom Engine Shooter
Free!
Freedoom offers classic Doom-style action: hunt demons with shotguns and rocket launchers in community-made maps. Free, open-source, and cross-platform on PC and mobile.


Freedoom is a free, open-source reimplementation of the classic Doom engine, offering both the original IWAD replacements (“Phase 1” and “Phase 2”) and a thriving map-and-mod community. It faithfully reproduces the fast-paced, corridor-blasting action of early 90s shooters while remaining entirely GPL-licensed—no proprietary assets required. Thanks to its modular design, you can swap in fan-made levels, replace textures, or even explore entirely new game modes, all running on modern ports across Windows, macOS, Linux, and more.
