Portal 2 Hints
How can I get that achievement?
1 of 7: You'll need to take the companion cube with you as you leave.
2 of 7: Go over to the edge of the floor that's nearest the big red button, then crouch down and try to pick up the companion cube. If you can, carry it through the exit door to get the achievement.
3 of 7: If you can't, go past the exit door and put an orange portal on one of the portal-friendly wall sections, then drop down to the button ledge.
4 of 7: Pick up the companion cube and drop down to the chamber's lower floor, then drop the cube and put a blue portal on one of the portal-friendly walls.
5 of 7: Carry the cube through the blue portal to get past the exit door and get the achievement.
6 of 7: After getting the achievement, you could drop the cube and then drop down to the button's floor to get a bonus message from GLaDOS about stranding yourself. However, there's no reward for that, and you'll have to start over again with the new companion cube that's dropped into the chamber's lower area.
7 of 7: Also note that if you carry the cube all the way to the elevator, GLaDOS will fizzle it, which gets you another bonus message.
