Kill 5 enemies with the melee attack while they're suspended with the grappling hook.

For this trophy you first need to know how to hang an enemy onto an object. To know how to do this just follow the method described above in the Hang em High trophy. The only difference here is that instead of killing the enemy by shooting him, you need to kill the enemy with a melee kill.

So when the enemy is hanging, walk up to him and constantly hit him with your whip by pressing the button. It will only take 3-5 hits to kill him depending on the enemy. If you are trying this on someone tougher than the usual soldier just soften them up with some gunfire before hitting them, 2 shots should do it. Do this 5 times and the trophy is yours
