Test Chamber 00 is an area in the Games Ending, which leads to the original Half-Life 2 mod office.


Like its counterpart in Portal, the test chamber consists of a statis tube where Chell (in this case, Stanley) awakens and began their adventure, a huge red button, a vent where cubes are dropped, a round door with the Aperture Science logo on it, which can be opened by placing a cube on the red button. There is an elevator at the end of the test chamber, however the Narrator decides not to let Stanley ride it, and leaves him there after sarcastically mocking Stanley for disobeying his narrations. Below the elevator is a round hole leading to the remnants of the office.


  • A well-known "Easter egg" is to pick up the radio from the glass room, then put it right next to the door, carefully placing the cube on top of it so that it leans onto the door. Then, when stepping on the button, if done correctly, the cube should fall between the doors and prevent it from shutting. After a while, the cube will shoot out from between the doors.
  • It is possible for Stanley to get stuck inside the test chamber by getting the cube through the door, although this is very tricky to accomplish. Should he manage to get himself trapped, The Narrator will be surprised to see that Stanley broke even the simplest puzzle. The Narrator goes on by leaving Stanley in the chamber since he doesn't have the intention to open the door.
  • Doing this glitch in Portal, however, doesn't make GLaDOS react.
  • It is also possible for you to get the cube stuck between the door, then the cube bouncing inside the room. It is still possible to normally open the door after that, but the narrator still says the "Broke the puzzle" dialogue. Entering the door after that makes the narrator act normally.
  • The sounds of the big red button is inverted to how it is in Portal. In that game, the synth tone plays when the button is pressed and the buzzer plays when it's released. However, this is the opposite in The Stanley Parable.
  • For those who have played Portal, one can see that there is no security camera above the arrow, due to the absence of GLaDOS. This could also be Valve's decision to prevent relation to Portal whatsoever.
