This is a list of all BO2 strats known so far. All Loadouts listed are NG+. In New Game, you can only use what you have unlocked so far in the new save. Any chances in a NG loadout will be posted.

Pyrrhic Victory Loadout: Death Machine, Storm PSR, Fast Hands/Longer Sprint/Hardness. Sticky Grenades (NG) -Using the Storm PSR makes it possible to snipe the mortar crew through the rock at the beginning of the level by charging the shot -In NG, you throw sticky grenades from far away, aiming high at a specific part in order to hit the mortar crew. Because they're sticky, the grenades won't roll away from the crew

Celerium Loadout: Chicom CQB, Death Machine, Longer Sprint/Hardness/FMJ. -After the flying section, it is possible to rush through all the fighting until you reach the destructible gates at the entrance of the facility. By killing the 3-4 enemies guarding it, every other enemy you pass is despawned, and it's only a matter of staying at the gate and waiting for your buddies to arrive. The gate can also be destroyed by any explosive, including your wrist grenades.

-The same despawn method can be done once inside the facility. Once inside and ambushed, run through everyone until you find the elevator, though in order to get the elevator going, the enemies near it need to be killed before you get too close or the elevator won't come up. Once the elevator comes up, killing everyone in it through the glass will despawn the enemies present on your floor, allowing for instant access to the elevator controls.

-After the firefight at the end, when the guy gets killed in front of you, no enemies need to be killed, just keep running until you are near Briggs, this will turn the game into an autoscroller and despawn all the enemies you passed. Getting in position at the cutscene trigger next to Briggs will get it going earlier.

Old Wounds Loadout: FIM-92 Stinger, Death Machine, Longer Sprint/Hardness/FMJ -After the assault begins and you go outside the base, there is a small building on the right with a stinger on the roof. In order to get the stinger, park your horse right next to the building that has the stinger on it, then get off it. After that, behind the horse there should be a small tent with a red cloth on it. Jump on the tent, then jump on the horse afterwards. The horse will give you enough height to jump on the roof with the Stinger, saving you valuable time. (skip to 3:00)

-(NG+) Because you already have the Stinger in your loadout, you don't have to run for it when clearing the first place with the two BTRs. The Death Machine also deals massive damage to the BTRs, blowing them up in less than 2 seconds, much faster than shooting a rocket into them. This massive damage also applies to the helo's that you have to shoot down.

-While interrogating Kravchenko, clicking the left mouse button at the "resisting" QTE will just get Mason to shoot Kravchenko instantly, saving a few seconds compared to waiting for the QTE to end.

Time and Fate Loadout: KAP-40, Death Machine, Hardness/FMJ/Longer Sprint -When playing as Menendez, there is a part before reaching the barn where 6 men are about to shoot a few citizens. 4 of them are lined up. Skip the shovel and Menendez will use the shotgun. Line yourself up with the 4 other dudes and hip-fire once, if you're lucky, you should be able to get them all 4 killed in one shot. Menendez will grab his machete, so killing the other 2 near you will let you get to the barn without killing anyone else on the way, you will know it works if the yellow objective marker appears on the screen after the 2 guys are dead.

-There is a point where a truck smashes into the gate where Menendez's house is. If you're quick enough, getting to the back of the truck and pressing F will get you into the gunner seat, the truck will drive automaticly for a bit, which is way faster than your standard sprint.

-When playing as Alex, there will be a small cutscene where Woods sees Menendez and rages. Instead of sticking around, keep running until you hit the courtyard. Kill everyone in the courtyard quickly using the Death Machine before the cutscene/dialogue between Woods and Hudson ends, and every other enemy will despawn and you'll only have to wait for Woods and Hudson to move up (8:32)

-Once inside the lab, run through EVERYONE inside, use the Death Machine to clear a path to the door that Woods will kick down. Once you're in the small room where the door is, all the other enemies will despawn and Woods will rush to the door.

Fallen Angel Loadout: KAP-40, Death Machine, FMJ/Hardness/Longer Sprint -Once the level starts and you gain control, you can immediately run to the part with the QTE where you have to push, without killing anyone. This isn't a hard task, though bullshit can always get you killed.

-(NG+) Once you're in the first stealth section, run past Harper's hiding spot and be almost under the Hind. If done right, you are able to shoot your Death Machine and destroy the Hind and the stealth section will no longer need stealth, and you can push past Harper easily. Do NOT let Harper overtake you though, if he's out of the water before you are, he will spawn way back once you do reach him.

Karma Loadout: Chicom CQB, Death Machine, FMJ/Hardness/Longer Sprint -(PC) Having 300 FPS or more in this level will make the slow-mo Club Solar shootout with the pistol speed up, this is because the game is badly optimized and FPS-dependent. (9:39)

-(NG+) Once DeFalco's location is revealed, you can snipe him from the ground floor using the Death Machine.

-(NG) Grabbing a sniper rifle from the armory is all you need to snipe DeFalco from the ground floor.

Suffer With Me Loadout: KAP-40, default M16, FMJ/Longer Sprint/Hardness -Once the invasion starts, get past the first trucks and wait a bit before heading forwards. Once you hear McKnight on the radio, rush to the base of the stairs. For some reason, this will teleport Mason next to you and he'll kick down the barrier to the stairs much faster.

-If you killed Kravchenko and didn't grab the CIA folder before this mission, the cutscene with Noriega being captured will end faster.

-During the hospital section, it's better to strafejump to the injured nurse than to walk all the way to her.

-Killing Mason here is much faster than letting him live.

Achilles' Veil Loadout: KAP-40, Longer Sprint/Hardness/FMJ -This level consists of just strafejumping and sprinting to your objectives, very simple.

-Harper dying is the fastest course of action, the cutscene is much faster and the switch to David takes less. Harper's death also speeds up several other levels after this.

-As Section, running into the middle saves more time than taking the left of the right sides. The only problem is the turret, which will auto-destruct once close, though. (5:47)

Odysseus Loadout: KAP-40, B23R, Longer Sprint/Hardness/FMJ -This level also consists of just running and strafejmuping to objectives, not much need to kill enemies.

-(PC) If you have over 300 FPS or more, the slow-mo Odysseus shootout cutscene will be much faster than usual, because the game is FPS-Dependent. (7:55)

-Killing Briggs is much faster than shooting him in the leg, it makes the cutscene with Section showing up shorter.

Cordis Die Loadout: KAP-40, Death Machine, Longer Sprint/Hardness/FMJ -(NG+) After the truck crash, the Death Machine is used to destroy the 3 CLAWs, a much faster alternative than the RPG that the game gives you

Judgement Day Loadout: KAP-40, Death Machine, Longer Sprint/Hardness/FMJ -In order to gain access to the main building, the Death Machine is used to kill the two CLAWs defending it.

-Further inside the building, incapacitate the two ASDs using an EMP grenade and rush into the main room. 5 Quads will burst through the upper windows, use the Death Machine to kill them all quickly. This will also open the doors to the computer room cutscene much faster.

-No enemies need to be killed whatsoever unless they are about to kill you. Rushing to the final cutscene where you confront Menendez will play regardless.
