The Dark Pit is an original arcade/maze game combination that originally came out on the Dragon & Coco in the UK. The game uses the joystick, and your object is to escape the 64 room Dark Pit maze. There are all kinds of monsters roaming in fixed patterns. You start the game completely unarmed, so you have to find both ammunition, and the gun, in order to do anything besides gather treasures, power, and keys. There are multiple weapons; the shotgun, for which you get 5 shots per ammo clip that you find, and 5 others that are based on power, which you get by finding lightning bolts. There are 3 colors of locks, and the corresponding colors of keys; you must have the right colored key to open a lock. It also features a top 10 score list.
The Dark Pit is also rather unique that it is one of the very few non-Tandy games that supported the Tandy Electronic Book peripheral. You switch your active weapon (assuming it is armed and ready to use), by pressing 1 to 6 on the Electronic Book (or on the keyboard, if you don't have one). Even the ability to switch weapons on the fly was pretty rare for Coco games.
