Took over an hour to hit
Note - This is much easier to hit off host but still pretty hard, it is possible to hit as host but substantially harder because the game physics/server is dependent on the host. Lowering fps for the overbounce to work makes it easier as well (Used 15 fps, on Xbox you need to do com_maxfps 5 as the fps you want you have to divide by 3 so I wanted 15 so I did 15/3 = 5).
I also have no idea if you don't take fall damage because the audio on my game wasn't working for some reason but you make the fall animation when you fall off something so I believe you might take damage.
Quake 3 overbounce bug present on CoD4 because it uses the same engine.
