I dont know... just thought about it randomly like that, what about some moving polygons? like a map maker could make a map with a bridge for boats or something (could be some doors or somethings) and when going back to home base the bridge lifts and you have to wait or to take an other route around to get a your flag. also perhaps "C" could be the "action" button and would open doors in a teams base or what ever... I'm sure there is a lot more places it could be used but right now I just want to go to sleep, so tell me what you think about it
