Countercurrent: Towards All Established Rules

The story takes place during the outbreak of a future world war, where countries form an alliance to develop destructive high-tech weapons. The weak country of Koloa was fiercely attacked by Kolodian's advanced military equipment. It was defeated across the board and was on the verge of collapse. In order to reverse the desperate situation, the country launched the top-secret "Operation Countercurrent", sending an elite spy team to sneak into the enemy's hinterland, risking their lives to steal the enemy's cutting-edge weapons secrets, in order to find the only chance to save the country and come back.
