I had to split several chapters to fit within the engine's limits
Few helicopter animations were cut because they didn't work for some reasones
There might be some small visuals bugs, please ignore them(I dont know how to fix them)
To make zombies run faster like in L4d you can use this mod Sprinting Zombies
