Guys,i think i bugged out xD
This happened to me on the sky 0 map.
One of the bots (if you time it right) can make you go flying by exploding one of the barrels by using the grenade launcher he has.
I don't think it's a bug tho. (sry for bad english my main language is spanish lol)
no u can replicate it by blowing up a barrel w/ the shotgun also, on any map.
