GunGriffon: Allied Strike cheats and cheat codes for XBox

Stage 2 hint:
While playing on stage 2, when the helicopter support comes in for rapairs and
an ammo refill, go to the drop site and try to protect the helicopter. Once the
helicopter shooted down, no more helicopters will come. Try to move always to
avoid hits and never stop or the mammoth class will shoot missiles to you.
They cannot get a lock on you if you are in move.
