The game is set on a fictional island called Malden (the setting of Bohemia's previous game Operation Flashpoint: Cold War Crisis). Mercenaries are deployed to Malden by two rival factions and has to fight over the remnants of a crashed space station. Game is similar to ARMA 3 but less realistic
Player can choose from multiple game modes. There is a mode called "Combat Patrol" in which player can fulfill procedurally generated tasks scattered across the island. Another mode "Link" is about fighting on a smaller scale, in which both teams have to hack a central computer. "Raid" is a battle of attackers and defenders. "Clash" is similar to "Link" but fighting takes place on a larger area.
