International Doom

International Doom logo

Small, functional and simple source ports, created with help, efforts and bits of code from people around the world. The project is based on Chocolate Doom and Crispy Doom, with significant additions from Doom Retro.

International Doom was previously known as "Russian Doom", but was renamed in response to the Russian invasion of Ukraine.

Major features

• Optional True Color render.
• Up to 6x (1200p) rendering resolutions.
• Uncapped framerate.
• Additional, darker gamma-correction levels.
• Support for OPL2, OPL3, MIDI, Fluidsynth and GUS music playback.
• In-game keyboard and mouse bindings.
• Various visual, audible, physical and demo enhancements.
• Compatibility with vanilla-engine demos.
• Removed limitations of vanilla engine.
• Support for nodes in extended format (ZDBSP and DeePBSP).

Compatibility

Gameplay features from "Physical" and "Compatibility-breaking" sections are putting changes in game mechanics, making it no longer 100% original. However, these features are optional and never active in multiplayer and demo recording/playing to provide maximum compatibility and prevent desyncs.

BOOM/MBF/MBF21 specifications are not supported.
