Portal 2 Hints
Side Area Notes
1 of 3: In one corner of the test chamber is a drop-off into a messy lower room.
2 of 3: Fall down there if you want to check out one of the game's many side areas. There's even a radio that'll start playing when you drop down.
3 of 3: To get back out, put a blue portal on the white concrete wall, then look up and into the test chamber so you can put an orange portal on a high-up spot on the back wall or ceiling. (Take the radio through the portal if you want to keep listening to it.)
