B67

B67 is a roguelike shooter where the player has limited visibility of the level. The player starts out on floor B0, and needs to descend to floor B67, killing all enemies on each floor along the way. The player carries two weapons, has a certain number of armor points, and cash. Cash is earned by killing enemies, and can be traded for resources at vending machines. A point of armor will absorb one shot.

By using weapons, the player increases their skill, which will improve stats like how much ammo can be carried. There are also achievements, which can increase view distance.
