It would also be quite impressive if when a crew member is KIA on the bridge he drops to the floor, or in bomb/rocket explosion - could even blown over board... Can you imagine what a direct bomb hit to the bridge would do the crew? - (the kind of thing that would earn the game and 18 certificate tbh)
Also it would not be fair to expect an anamiation for other crew member to carry an injerued man below deck... they could just be teleported (manually)
