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

There are 2 very easy ways to earn this trophy.

The first way is to boost it with 2 boosting partners - the booster goes on his own against the other two, plays a 5 minute match, and ensures he finishes with a score greater than the other team. Do this by killing them a few times, or for example on the Open Range map, destroy the satellite dishes and other ground targets dotted around. Do this for 10 games, and you have your trophy. This way is my personal favourite because if you do it for each person, you have played 30 games and are 30% of the way to unlocking Veteran. Also, you can have the other team pick identical planes to work on Copycat at the same time.

The second way, untested by myself but proven to work for others, is to host a game, and if you are winning near the end, kick one of/all your team from the server. This way you will finish the game with less players and it will count towards the trophy.
