Shooting this type of enemy will cause it to chase your man very quickly. They can be destroyed by using bombs, but a new Anngrer will be created in its place at the bottom of the screen. These enemies can travel in and out of the tunnel system wherever they choose. Sweepers - Along with additional enemy fire, these foes appear in pairs on the left and right sides of the tunnel along if the bottom and top portions of the screen are connected by one continuous tunnel. They will line up with each other on either side of your SWAT agent and fire at him.
Sweepers require multiple shots to be destroyed.
Your man, a futuristic SWAT agent, can shoot blue tunnel sections to destroy them. Tunnel sections on the opposite side will whiz off the screen if unobstructed or rest against another tunnel section if one blocks it. Pink blocks which are no longer connected to the bottom turn blue and float toward the top. Additional bombs are earned for every 10 blue tunnel sections destroyed. The round ends when a predetermined number of Blockers are destroyed.
