Gravity flipping level

I don’t know how they would program it into their engine, but I would absolutely LOVE a level where you’re running through some large tunnel area filled with sentinels, and certain parts of the tunnel are blown out so you ride these gravity lifts up to the top of the tunnel where the gravity then flips and you’re running on the ceiling. So like, you’re shooting at the sentinels that look upside down to you, and if you look up, you’re actually looking down into a pit. At some point you see some pelicans fly by but they’re upside down. It could be pretty amazing.

If gravity atracts you to the ceiling, you will land on your head and break you neck?

so wouldnt you at least lose some shielding from the impact?

sounds like…portal 2?
