Odamex is a free and open source port for the classic first-person-shooter Doom. The goal of Odamex is to emulate the look and feel of the original Doom executables while offering a broader expanse of security features, personal configuration, gameplay options, and editing features. Odamex can run on a wide range of operating systems and hardware, so players should be able to play on almost any platform.
