Death Chamber

Death Chamber is Knuckles's second to last stage only playable as him in Sonic Adventure 2 and Sonic Adventure 2: Battle. It is a treasure hunting stage and can be unlocked in 2P Battle after beating Hero Story.

Overview
The first goal to this level is different from all the other levels belonging to Knuckles. Instead of finding Master Emerald shards, he's actually looking for 3 keys to unlock the door to the rocket to take them up to the Space Colony ARK. This level, like many others in the game, has quite a few ghosts in it, some being cute looking, but when punched, red-eyed ghosts burst out of it. King Boom Boo is the following boss after this stage and must be destroyed by light. Right after this you must fight the Egg Golem. The music is Urban/Rap(Warning!--Mild lyrics are in this stage!).

There is another version for the dark story for this stage. The stage is for Rouge, and she too also has to find keys to open a door.
