You will receive a task in WW2 Tunnel Shooting to go into the tunnel and smoke the enemy from there. The main part of the enemy army is defeated, but some units hid in underground subway tunnels and hope to wait out and then leave under cover of night. This cannot be allowed and you will prevent it. To complete the levels you need to destroy a certain number of goals. To get started, you get a gun at your disposal. When funds appear, you can buy a machine and things will go livelier. You need a quick reaction and an accurate hit.
