- Easy A.C.E.S. points
Begin a Terrorist Hunt game with 'Lone Wolf' off. Set the difficulty to Realistic, and use the Killhouse map. Set the amount of enemies to low-medium, then begin the game. Make sure to bring C4 for the Assault points. At the begin of the map, run up the stairs, and place your teammates at the top of the first flight of stairs. Immediately use the right side of the wall as cover. You should be able to see a rappel rope on the left side of the wall. Next, do one of the following things to get A.C.E.S. points in the indicated category:

Go to Act 5, Scene 1 in Story mode on the Normal or Realistic difficulty. Kill all the enemies on the roof, and go into the building. When you enter the building, you will reach a checkpoint. There will be a staircase in front of you. When you go down the staircase, there will be a door with three terrorists talking inside. Next, do one of the following things to get A.C.E.S. points in the indicated category:



In the 'Ambush' mission, get to the end where you have to order one of your teammates to defuse the bomb. Order him to do that and stand beside him. He should complain about you standing next to him. Then, have your other teammate regroup, then tell him to throw a grenade at the door in front of the bomb. You should get two kills. Look above you. There should be a person about to go on the turret. If you kill him, he keeps respawing. This is an easy way to get Assault points or any other desired A.C.E.S. points. Notice: You will get more A.C.E.S. points on the Realistic difficulty.


In the 'Negotiations' mission, once you reach the part where you have to defuse the bomb on the door, have your team keep pushed at the base of the stairs. Then, advance up the stairs, and stand a few feet back from the double doors. Aim at the bottom of the doors, and throw a grenade. Back away from the grenade fast so you do not die. When the grenade goes off, a delayed rumble will occur, and you will get A.C.E.S. points. You will get more A.C.E.S. points on the Realistic difficulty. You will fail the mission because it states that you 'Disobeyed a Direct Order', but do not worry -- you will not lose any experience and can just reload the checkpoint at the bottom of the stairs again. Repeat this as many times as desired.
