Strategy Guide/Walkthrough/FAQ


Gold camo

Reach Level 31 in Multiplayer mode for a weapon by getting 1,000 kills with it to unlock the Gold camo for the weapon.

Secret killstreak

Get a 25 (24 with Hardline) killstreak using only your gun/knife/equipment (killstreak kills do not count) to get a M.O.A.B. (Mother Of All Bombs). When activated, it will kill all enemies on the map, no matter where they are, as well as disable the enemy’s equipment, electronics, and pointstreaks for one minute. Additionally, the team with the person who calls in a M.O.A.B. will get double XP for the rest of the match.

Easy XP

Once you reach Level 20 in Multiplayer mode, use the Specialist Killstreak package to get a lot of extra XP. Create a class with the Hardline perk and use the Specialist Killstreak package. You will get extra points at kills 1, 3, 5, and 7. It will also help you complete the perk’s challenges and the Specialist challenges for each perk. You will be completing the perks, and each perk has a Specialist perk challenge to it. For example, if at one kill you unlock Assassin, you will be completing Assassin challenges while also completing the “Assassin” Specialist challenge. You will get a lot of XP as you complete these challenges in addition to the 200 XP you get for kills 1, 3, 5, and 7 each time. This works best in modes where you get a lot of kills. Additionally, you get extra points for kills 8, 9, 10, etc. as long as you have all the perks enabled and have not died.

Easy Blast Shield Pro

Throw a Flash or Concussion grenade at the wall so it bounces back at you and stuns you. It will be counted as deflecting an explosion for the Blast Shield Pro. Note: This glitch was done on an unpatched version of the game.

Easy SitRep Pro

Once you unlock the Trophy System tactical equipment, assign it to a class, and deploy it. Then, knife it, and it will count towards destroyed enemy equipment for the SitRep Pro. Note: This glitch was done on an unpatched version of the game.

At the multiplayer main menu, select “Options”, then disable the “Theater Recording” option to help reduce lag during online games.

Easy “Birdie” achievement

The best place to get the “Birdie” achievement is on the “Carbon” map in Special Ops Survival mode when two helicopters spawn in Round 6. Before reaching Round 6, buy 10 claymores and a turret. In total, you should have at least $10,000 at the end of Round 5. Go to the air support crate inside the building, and secure the area with your turret and claymores before starting Round 6. Then, start Round 6, and use Predator missiles to destroy the helicopters ($2,500 per missile). Stay in cover where no enemies can see you. You will get the “Birdie” achievement after shooting down the second helicopter as long as you took no damage at all during the round.

Easy “Get Rich Or Die Trying” achievement

Instead of trying to save up $50,000 by playing solo, play a Special Ops Survival map with two players. Once both players have a total sum of $50,000, go to the shop, and have one player give the other enough money so they have $50,000 to get the “Get Rich Or Die Trying” achievement. Then, give the other player enough money so they have $50,000 and get the achievement as well.

Easy “Jack The Ripper” achievement

In the “Stronghold” mission, when Price tells you to turn your night-vision on and he turns off the lights, quickly run around knifing the enemies to get the “Jack The Ripper” achievement.

Easy “Strike” achievement

At the beginning of the “Persona Non Grata” mission, after leaving the starting area and going down a set of stairs, you will reach a large courtyard. Run to the left side, and kill the enemies that are in your way. Six enemies will come out of an alleyway and stop in front of a door. Cook a frag grenade, then throw it in-between them, and you should get the “Strike” achievement. If you do not kill five of them and get the “Strike” achievement, simply reload the checkpoint and keep trying until you get it.

In the “Return To Sender” mission, when you see a bunch of enemies run across the screen from right to left during the sandstorm (when Echo Team says “We’ve located Nikolai’s chopper. It’s a half click south of your position.”), reload the checkpoint, then throw a flash bang at them, and toss a frag grenade to kill them all and get the “Strike” achievement.
