Check out the link above as I found a video to what may be an upcoming NEW game mode in Combat Arms. Hopefully we'll get lucky and it will be in the next content patch.
The new game mode named, Scenario consists of the following:
You and a human team are pitted against A.I., controlled opponents with a limited number of lives. Ammo pick-ups lay on the floor, once the enemies have been cleared out of a certain section you move to the next one.
