Portal 2 chapter 8 test chamber 11 bug?

[jeandrek]

Hello, I accidentally discovered a way to complete Wheatley's test chamber 11 without using any of the cubes by floating to the roof ceiling using the excursion funnel, crouching, and then I can fly across the ceiling before falling on the lift and completing the chamber. This seems pretty strange to me, but I am using MacOS and I'm not sure if this is an actual bug or I found a legitimate solution?

Hello @Jonathan50, this quirk has been around since release and is not OS-specific.

It's also used a couple of times by speedrunners of the game as seen at https://youtu.be/de8DkNOkNUQ?t=4276.

[jeandrek]

Ok, does that mean you are going to leave it like that?

[kisak-valve]

At this point I personally do not expect it to change. It's not for me to decide because I'm a moderator for these issue trackers, not a Valve dev.

Alright, thanks.
