Call of Duty: Modern Warfare 3 Xbox 360 Cheats and Tips

Hold x at the title screen and b and you will have unlimited ammo

You can reduce latency by disabling the replay feature. To do this, use the Options section of the Multiplayer menu and select Theater Recording. Disbale it, and the game will not be saving a replay of your matches, which will help reduce lag.

Obviously you then won't be able to review your games.

First go to dome on multiplayer run to the building with the dome on top look on the sides of the building"both sides" when you find this blue thing on the wall and jump on it "it takes a couple tries" after that look to your right then jump on the pipes by the window jump on the window and look up jump in the little space and go inside the dome run to the spot with the fence on both sides go in it and your partly out of the map

If you are in survival and can't beat a juggernaut I got my own cheats to smash him.

1. Get 2 player or 1 but 2 is easyer to kill the big guy

2.both players get a riot shield squad

3.both players get sentry guns does not matter wich 1

4.get a M6OE4 and both players shoot the juggernauts head

5. If your squads get killed just buy more

6.doing all this I got up to wave 25

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

This hint will help to increase your accuracy during speed course missions in special ops.

Firstly, grab 2 primary weapons that have a fair amount of ammo and that you are fairly used to.

Secondly, whenever you shoot, ALWAYS look down your sights or you are just wasting ammo.

Thirdly, whenever you are not shooting targets always make sure you are sprinting, it's a speed test after all.

Next, whenever you are shooting targets just make sure to slow down (stop running) and also take your time. If your able it helps to let go of LT, re-aim and snap it back again instead of holding it down and aiming waiting a longer time to see the target. It doesn't seem like alot of time, but it adds up.

Make sure you ..

If your playing campaign at mission 15 and on favela in mw2 or mw3 if you find a fake monkey bomb or random box for bo2 zombies press XYYX and if you do it 5 times you will here a sound that says leave the box alone

(Ps it is real in campaign find two buildings and look behind it and you will find it)

If you ever see a enemys bouncing betty run and jump over it on the sides and wait until any enemy comes and walks over it he dies(make sure it's not your bouncing betty.

FIRST THINGS FIRST you want an acr 6.8 custom(ACOG and grenade launcher). Next you want a grenade launcher sentry gun. Now you want set it down on the end of a dead-end street.Lay down behind it. You can still shoot BUT I recommend just sitting there. It has to be after the choppers and it won't work on jugs.my cousin the mighty Monte found this out and we made it to wave 26.

If your going for trickshot and a hitmarker well you just found the right person Noromovial here's what I mean on the map rust or favela hit x and yy and rt at the same time if you hitmarker or actually hit. It's your lucky day

Go to the back of the map stand on the wall with a riot shield out and throwing knife get your mate to stand the other side of the wall with his gun out. Stand behind the tree and whack with the riot shield and get your throwing knife out
