Combat Arms - Neptune Map Flythrough #2

The completion of this top-secret project has been leaked to enemy squads, who are organizing to seize and unleash the destructive capabilities of the submarine’s nuclear power. Players can fight in the corridors above the Submarine, or snipe from the balconies overlooking it. Soldiers must tread carefully, as those who attempt to access the map’s Submarine level will self-destruct.
Action fans can now infiltrate the newly constructed submarine base in “Combat Arms,” Nexon’s high intensity free-to-play first-person shooter game.
