That's what spy heaven looks like I reccun.

It's actually a corridor of death if you do not bother jumping ontop of the sentries. (Can you even duckjump ontop lvl3 sentries? I don't remember)

There was a guy stuck between the wall of sentries, a medic and me. Melee time.

Yep a lvl 3 sg is the same size as a lvl 1, also all classes jump just as high as any other. Accept for the scouts double jump. So if the engie can get on his gun any class can.
