Easy A.C.E.S. points
Start 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 start the game. Make sure to bring C4 for the Assault points. At the start 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:

Assault

While still in cover, throw a C4 out so it lands at the bottom of the rope. Wait until someone starts to climb down, and halfway down, detonate the charge. This will get you +3 Assault points for each kill. Once you run out of C4, use explosives.

CQB

Just blindfire the enemies rappelling down the rope. Each kill in blindfire gets you +3 CQB points. Alternatively, wait until the enemies reach the bottom of the stairs and start to move towards you. After they are relatively close, pop out from the cover and kill them. This will get you +3 CQB points.

Marksman

Simply shoot the enemies as they are climbing down. A light machine gun is recommended as they rappel down quite often. Each kill while they are still on the rope gets you +3 Marksman points.

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:

Assault

Open the door, toss in a C4, and detonate it for +9 Assault points. Then, reload from the checkpoint and repeat as many times as desired.

CQB

Use a SMG with a good sized clip (like the P90 or Type 05). Enter the room, run forward a few steps, and shoot all three terrorists for +9 CQB points. If you have trouble killing all of them, shoot the guy on the right first, and then the two facing each other (the guy on the right is the one who usually kills you). Then, reload from the checkpoint and repeat as many times as desired.

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. Note: 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 hold 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.

Getting into train in Killhouse map
There is a broken down train at the southern end of the map. Take cover behind the barrels inside. Release LT to move off of the barrels while moving forward. Click the Left Analog-stick to stand up, and keep moving forward until you are on the barrel. Your head should be outside of the train. You can snipe people on the stairs or coming down the fastrope.

Easy "Haute Couture" achievement
To get the "Haute Couture" achievement, you must be an Elite. When you become an Elite, you will get custom camo. All you have to do is put one on to get the achievement.
