In addition to these plays, we were experimenting with another idea that brought interesting results:
Solo:
One player rushes while the others camp. The player who is rushing can act as a scout and report back the position of the other team. The play can be announced like, "solo orbital", if I were the player who was rushing. This play can then be followed by another play if it is decided that the rest of the team should do something other then camp.
We generally were using simple one word calls for each play, e.g. rush (group rush), split (split rush), stealth, camp.
