15 Impossible PlayStation 4 Trophies Nobody Unlocked

13. Is That A Knife? - Mercenary Kings

Thanks to the deluge of 2D side-scrollers invading your games library left, right and centre, Mercenary Kings didn't take off as much as developers Tribute Games would've hoped, but that didn't stop a devoted following forming around its extremely fun gunplay, experimental level design and fantastically-animated pixel aesthetic. The trophy listed here is for really getting your Crocodile Dundee on, as you'll need to take down the already very challenging Steel Soldier with just your knife. There are a bunch of different blades you can spec with various status effects to pull it off, but you'll have to be quick at evading the Soldier's attacks in the first place, as he only takes damage from behind.
