Death Chamber is the twelth stage of the Hero Story in Sonic Adventure 2 and Knuckles' fourth stage. It is the same as Rouge the Bat's Dark Story stage Egg Quarters. The music for this stage is "Deeper".


After locating the entrance to Dr. Eggman's pyramid base, Sonic and Co. find that the door to a rocket that will take them to the Space Colony ARK, where Eggman is located, is locked. Sonic persuades Knuckles to find the three keys to the door so they may proceed.


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 a door. This level, like some others in the game, has quite a few ghosts in it. King Boom Boo is the following boss after this stage, and Egg Golem following right after that, played by Sonic.


The upgrade in the stage is the Hammer Gloves, which allow Knuckles to break open iron boxes.
