Critical Ops is a first-person shooting game with challenging maps that can maintain the fairness and justice of the game itself. You can also play with your friends in the team leaderboards, or you can use your outstanding skills to top the personal leaderboards. The result of the battle is the cooperation of individual skills and teams.

The game has two opposition alliances (representing anti-terrorist forces) and "breakthroughs" (representing terrorist forces) competing against each other. One team can win by completing a given objective or by eliminating the other team. The game features team deathmatch, disbandment, shootout and other modes. Players can earn coins to buy skins and other items.
