Just played MW3 Free For All and 2 players where stood on the tail fins of 2 planes at the airport just picking off players as the ran around the airport. When shot at they were invincible. They were DREAD` MR.HAMBU and the other was DREAD` WARRIOR. Is it possible to get up there without a cheat, but thet were definatley invincible as they made no attempt to move. Have screen shots of their kills. Idiots like these ruin the game.
