Previous: NONE TEST CHAMBERS Next: Test Chamber 01

Test Chamber 00 as of Portal 3 is mainly the same as Test Chamber 00 of the first Portal game, but the cup, clipboard, and radio are moved, or in the case of the radio, gone. This is a reference to what players often do in the first Portal game, though it isn't even the original chamber. Also, the second part of the chamber seems to be unfinished, as it has no ceiling. This chamber introduces the player to: Portal controls, Weighted Storage Cubes, Super Buttons, and Emancipation Grids.
