Legend of the Chambered/527
Build "527" is the only leaked prototype of the cancelled game Legend of the Chambered.
The game generates a small "dungeon", in which at the start point numerous items are located. These items can be equipped to increase attributes, that do not seem to have effect. Beyond this, the game is very basic, not even giving the player the ability to attack enemies, though the player can be attacked by them. There is an exit, but it leads to an almost empty area.
