Test Chamber 20 has three laser beams that you'll need to redirect into three receptacles to open the exit door.
- How can I get all the beams redirected with only two redirection cubes?

Test Chamber 21 is actually a deadly trap, but Wheatley will show up and help you escape it.
- When is Wheatley going to appear?
