Catacomb [Bad Colours]
What is Catacomb [Bad Colours]?
This is a version of the classic top-down shooter Catacomb, labeled here as "Bad Colours" due to a noticeably altered or glitched color palette from its original EGA and CGA graphics. The game was originally developed and published by Softdisk in 1989 for the Apple II, later ported to IBM PC compatibles. It was programmed by John Carmack, who would go on to create Wolfenstein 3D and Doom. The "Bad Colours" moniker likely indicates a hack, an emulation artifact, or a user-modified ROM that changes the visual presentation. You're playing an unofficial take on this early first-person-shooter ancestor, not a clean commercial release, but the core action and code remain intact.
How to Play Catacomb [Bad Colours] Online
Getting Started
You start in a small brick room with a wall of stone ahead. Move with the arrow keys and press S to fire your magic bolts at the floating skulls and other enemies that appear. The goal is to find keys to unlock doors, collect treasures, and reach the exit to the next level. The maze is viewed from a top-down perspective, and you can strafe by moving sideways while facing a direction.
Combat is simple but quick - enemies move toward you along set paths, and your shots travel in a straight line. The game expects you to learn enemy patterns and use the environment to avoid being cornered. Watch your health indicator (a row of hearts) and grab potions when you find them. If you die, you restart the level with full health.
Because this is an unofficial version with altered colors, some visual cues (like key colors or door types) may be harder to read. Focus on the shapes and layout. The game's core loop of explore, shoot, collect, and advance is unchanged from the original 1989 release.
