stuck on the Hunted level..
im at the part where you have to shoot down a helicopter with the stinger.. ive got the stinger in my hands and when i try to shoot it, it keeps saying that i need a target lock.. but it wont allow me to lock onto it.. anything im doing wrong? restarted the level a few times but wont do it :(
Make sure ur aiming and follow the heli around keeping it in the circle then wen it makes the lock on sound like on the javalin... FIRE
tried it a few times and its not working...
