Ghost vs ghost? O.o"

I was thinking about it, What if GR uses the camo-suit or whatever tecnology against those ghosts from BL?
But, you will say:
"meh this is a bad idea cuz it'll take too long to kill everybody and blah blah blah"
sooo, give'em guns
yeah, you heard me, give'em guns, and make those teammates visible to the player.
but, a gun cannot have camouflage huh?
let it without it, so floating guns with inivisibaddy people using'em =D
sooo, invisible people with visible guns shooting eachother (the melee guns can be invisible) cannot get worse or can it?
make it SnD xD
