its not AP, you are just bad at the game. you need to take the helicopter out fast, so you need to aim and shoot as quickly as possible to take down the helicopter before it kills you. it takes about 8 rpg shots to kill it, more or less
The game doesn't register the hit at the front, it registers the hit at the tail, so if the rocket goes through the helicopter then to the tail it's a hit.
iluvfupaburgers you must of been bad at games in the past and now also one of my friend's had trouble with the helicopter as well. sorry won't happen again. Thank's problem solved and i was hitting the window got no where.
yeah, i am so bad, i already beated the game twice, while you just figured out you were not aiming at the correct spot and could beat the helicopter, and therefore blaming your card
