id Software's Doom pioneered the modern first-person shooter genre. Released in 1993, it was a quantum leap in game engine technology with fluid and — at the time — incredibly realistic 3D graphics.

While you can still enjoy the original Doom and its progeny today in an emulator, modern games are held to higher standards of visual fidelity, usability, and multiplayer features. Doomsday Engine exists to refresh the technology of these classic games while retaining the core gameplay experience.

  • The “cubeshot” console command that generates environment cube maps only drew one of the cube faces.
