Mercenary Kings Gameplay on the Playstation 4 with commentary by me. In this video you will see the beginning of Mercenary Kings an indie game that was available as a free download as part of April 2014 PSN Plus game collection for the PS4. br This game is like a Metal Slug and Contra combination because you get a little of everything specially been able to make your own weapons from items dropped by the enemies. br br All Rights belong to Tribute Games.
