You knwo what C3 needs? Team Sneak! That's how they can step up the MP!
One team is invisible nano suit guys with only melee knives, and tranq guns. Other team is fully visible using assault rifles/smgs/etc.
I would have an ORGASM if I could be invisible and find a group of the visibile peeps to kick a car on.
Oh and of course team sneak is an objective game type where the invisible peeps gotta grab 1 of 2 flags and bring it back to their base. If anyone on the invis team gets shot, then you can see everyone on their team for 5 seconds, and everyone goes back to invis only when the timer drops back to 0, and no one resets it by being shot at still.
Crytek, carry on the MGO torch!
