No worry man, the game is pretty fun, had a blast being really stressed, kinda reminds me of the multiplayer in Cry of Fear.
Maybe it would be interesting if the medic could revive people in PVE, along with the self revive thing.
IDK, just an idea.
Oh, also, other players kinda bob up and down on the elevators (I imagine it's from the desyncing), but that's so minor i forgot about it.
