The game is based on the 8 bit dungeon crawl computer game. The game is played on an 18x18 surface. One player takes the heroes, the other the dungeon. The game is scalable so you can have more than 2 players at a time. The dungeon gets a portal (spawn point) for each hero taken. Heroes explore the dungeon, kill monsters, get loot, hearts and potions (not necessarily all at once though) and search for treasure chests.
As the game progresses the power of the heroes grows as they gather loot and kill monsters, but the power of the dungeon increases as it does damage to heroes, going from 8 bit to 16 to 24 ultimately leading to boss battles and the 'final fight'.
