Ack Ack Achievement/Trophy Guide
During the second mission 'Operation Cobra
' you will come to a point where you will man a AA Gun
and will need to shoot down planes that are firing upon you. The objective here is to destroy all 20 Planes
(and no, this isn't as bad as the Battlefield One achievement) and can be done by restarting checkpoints if needed, however if you miss one and there is a checkpoint you will need to restart the mission.
Thankfully, there is a pattern to the planes and it is as follows:3 RIGHT - 3 MIDDLE - 2 LEFT - 2 LEFT - 3 MIDDLE - 2 RIGHT - 2 LEFT - 2 LEFT - 1 MIDDLENote: This achievement for Xbox didn't unlock for me until AFTER I completed the Mission so pay extra attention to if you actually saw them blow up or were just on flames and if you're not sure simply restart the checkpoint.
Here is a video guide for you.
