Missiles are hard to kill sometimes, luckily you can die to them while going for this achievement. Eventually while going through BattleZone missiles will begin attacking you. You’ll need to kill ten to get the achievement. As mentioned before there are a few things you should know when trying to kill missiles.
Missiles will always spawn in front of you and will always use the same path of movement to try to hit you. They move pretty fast so trying to avoid them is pretty much out of the question so you’ll have to try to shoot them down. Missiles will always zig zag at you and as mentioned before use the same pattern, try to get the pattern down and then fire at them as they get closer for a larger target. If you don’t have very good aim wait until the very last second before the missile hits you and then shoot. Since it’s about to impact it will be facing right at you and be right in your crosshair (assuming you didn’t move.)
