Tom Clancy's H.A.W.X. 2

This can be tough if you try it yourself, although it is doable. The easiest way however is to do it with other players online, whether they be boosting partners or just random people. Select 'Player Match' and filter the results for Survival, or host your own game. Either way, the Moscow map is generally regarded as the easiest. You just have to kill 10 waves of varying enemies, both ground and air targets, so be sure to have the weaponry for both, If you have a team that even has half a clue how to play this game, you should be all set. Just be aware that if your team runs out of respawn tickets (shown at the top left of the screen) then you will fail. Also, you must destroy every enemy from every wave, and the sooner the better, because the last wave must be destroyed in 2 minutes - otherwise you will fail. Flying in constant circles won't cut it for this trophy!

It helps if you all have some good team support abilities, such as repair drones - these help greatly with keeping everyone alive.
