So I just played a game of Team IA on Skyline, few bits in I was on that small roof near the greenhouses trying to jump to the top ledge near the water fall thing, (Hopefully you get the idea). Anyway, I took some form of damage, lacked the energy to make the jump, landed on the ledge under the proper ledge, and entered a complete no-clip mode. I could not jump, I could sprint, and I got like, 10 kills in a row (It was hilarious) till I finally died cause i had no ammo left.
I wish there was a theater mode so I could record it, I was able to no-clip through the entire level, i could not go up or down, just locked at the altitude I was at.
Figured I would mention it!
