Odamex

About

Doom is a 1993 first-person shooter developed and published by id Software for MS-DOS, the first game in the Doom franchise. Odamex is a GPLv2 Doom source port focused on client/server multiplayer over the Internet, with network compensation (unlagged, interpolation and prediction) and support for up to 255 players. It is based on CSDoom 0.62, which is based on ZDoom 1.22, and runs on Windows, Linux and macOS.

How it differs from the original

It adds game modes such as Team Deathmatch, Capture the Flag, Horde, Survival and Last Man Standing, and competitive features like warmup and round systems. It also removes most vanilla static limits, supports Boom, MBF and some ZDoom features, and adds widescreen, true-color rendering, resolutions up to 8K and uncapped framerates, while offering settings that emulate vanilla Doom, Boom or ZDoom physics.

Getting started

Download the latest release from GitHub or install it from Flathub. Building from source needs CMake, SDL2 and SDL2_mixer, and the repository must be cloned with its submodules.

Additional notes

Features

It can play back vanilla Doom demos and record client netdemos with playback controls.

Features

An in-engine WAD downloader and on-the-fly WAD loading are built in.
