Online demonstration running Doom 3 Demo
Hint: use "HOME" key instead of "ESC" key
Use the HOME key to go to the main menu or skip cinematics (instead of ESC key), and Tilde key (~ or ²) to open game console.
Arrow keys are "WASD" by default, and can be changed in-game.
Resolution is 960x640 by default (3:2 aspect ratio), and can be changed in-game. Use Alt+Enter to restart video (ie. "vid-restart" command).
Use the top-right Fullscreen button to enter fullscreen. Note that this will just rescale the canvas, and not change the actual game video resolution.
