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.
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.
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 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.
