Find weapons and destroy the giant ants. Instructions on the screen will help if you are playing for the first time. The ants patrol the area until you get too close or you start shooting at them. If you are in the tank the ants will detect you from a farther distance.
If an ant is alerted to your presence, other ants will soon follow.
