Tomb of the Aztecs is a roguelike with raytraced graphics and real-time combat, a change from the usual turn-based tile movement employed by other RLs. You play an adventurer who is on a search for the Orb of Popocatepetl, rumored to be hidden somewhere inside the lowest level (sixth floor) of the legendary warrior's tomb.

There are no items, weapons or armor to pick up, other than ammunition for your fireball cannon stored inside treasure chests. You can regain some health by walking over a chest and plundering its contents. The save function is accessible by pressing the escape key and bringing up a pause menu, although players will always resume their journey from the starting position of a level immediately after restoring a save game.
