An unrelated programming glitch, is in escalation, that allows players to pass through the forcefields if they transform into it at the right moment... as well in Remnant if you jump to the floor in the main 'room' and transform as you land (which kills you if you are a car because you fall through to your death).
(it has been good to see up to a thousand people on PS3 WFC since TF3 came out, but it's slowly dropping off again - I think if the TF3 game had escalation, it would have been the death of WFC's version)
