Is there call of duty modern warfare 3 cheats?

Answer 1

There's no cheats as there are glitches, which people use. A few like getting inside a tanker and camping (patched), or tighter grouping of bullets from a high rate of fire gun by starting with zoomed down using a sniper then going prone and then switch to your secondary then you wont miss a shot (patched). There going fast, so if you want to use one before there all gone then YouTube will become your friend. :)
