Shades of Doom is an Audio Game produced by GMA Games in the early 2000's and based on the mainstream game Doom.
Shades of Doom provides examples of:
- Die, Chair! Die!: large machines can be blown up in the game using weapons.
- Easy-Mode Mockery: the first two difficulty levels are labeled "It's my turn daddy" and "Don't hurt me."
- Enemy-Detecting Radar: since it is by definition, an Audio Game, this serves as an aid to blind players.
- Flushing-Edge Interactivity: there are toilets in the game. Flushing these will spawn a gelatinous blob.
- Game Plays Itself: letting the game idle when in the main menu will start the character exploring the maze of corridors until you press a key.
- Item Drop Mechanic: a majority of the enemies in the game do this.
- Level Editor: this exists at a rutimentary level in that you can only create your own maps using ascii symbols.
- Training Dummy: The "easy" difficulty level allows you to turn on training mode. The monsters will not attack or move to attack unless the player attacks first.
