In Atari 2600’s Crypts of Chaos, the goal is to battle monsters within the crypts, collect treasures, and successfully escape.
The starting depth in the crypt depends on the game selection. Choosing game one, two, three, or four places you at levels five, nine, thirteen, or one, respectively.
You have various weapons at your disposal: a sword (unlimited attacks but ineffective against wizards), a wand (limited attacks, depending on game selection, and ineffective against dragons), a ring of power (limited attacks, depending on game selection), and a peace symbol (unlimited uses, but awards no points and is only effective against trolls, eyes, wizards, and dragons).
You will encounter enemies such as trolls, frogs, snakes, skulls, blobs, eyes, wizards, and dragons. Level one features only trolls, level two has trolls and frogs, level three includes trolls, frogs, and snakes, and so on, until level eight and below, which contain all enemy types.
