Unused Graphics


A striped wall with blue and red. Possibly meant to be used in the first "episode" of the game (Floors 1-19).

Unused Sprites


Sprite Number: 0

The demo playback was supported in the one-level demo version release. The full floppy and CD versions remove the demo playback feature and have the sprite in question unused.

Placeholder Maps

While the floppy version of the game has 36 level slots, the CD-ROM version has a full 60, ala Wolfenstein 3D. However, some of these level slots are occupied by placeholders. Strangely, almost all of these placeholders are unique!
