Uncharted 4: A Thief’s End™
Wingman (BRONZE)
Perform 10 combo buddy takedowns #PlayStationTrophy

A combo buddy takedown is basically when an ally is holding an enemy and you defeat it, or when an enemy is holding you and an ally helps you, or you and an ally punch an enemy at least once.
There’s a very good chance you’ll get this from regular play, but in the case you don’t, go to encounter select and do Laundry Fight from Chapter 2 on Light difficulty. Just go around, giving a punch to an enemy an ally is fighting and the trophy will eventually pop.
