Like other third-person shooters, Mercenary Ops implements cover-based mechanics and an active reload system as the foundation of the game's design. Along with these familiar gameplay elements, the developers added the precise control and aiming abilities found only on the PC. In addition, the game was enhanced by adding destructible cover, an encumbrance system and maps designed with multiple threat vectors to shake up the stop-and-pop gameplay often found in third-person shooters.
Combat in Mercenary Ops puts an equal emphasis on both competitive play and team-based cooperative missions. In competitive multiplayer, up to 16 players can faceoff in five different, intense game modes, while in co-op, teams of 3 - 8 players take on hordes of AI controlled enemies and mini-bosses in a fight for survival.
