The object of the game in Undercover Ops is to not be seen so you can carry out your deadly knife attacks. Use the arrows to move left and right. Up and down will jump you or it will get you to climb up, down, or to use objects like monkey bars. Use the space bar to unleash your deadly attack. The one catch is that you cannot be seen, or you will die first. Be sure to sneak up behind people in order to get your kills and keep the game going. See how many levels you can continue your stealthy pursuit of revenge and play Undercover Ops now.
