Aliens have been landed near Viper City! NastyMan cannot stand the alien and decide to kill them all! He therefore, steals a tank from an army base and set his plan to destroy the new intruders!
Your plan is to destroy all the aliens in the stage and then find and reveal the exit door to the next stage by blasting one of the exploadable object on the stage. Controlling NastyMan is used by the mouse... Just make his tank scroll after the coursor in the direction you ought. Left Button to shoot bullets from the tank's cannon. And B on Keyboard to plant a bomb in order to destroy static objects in the path. Shoot an alien to damage his tank, then, get your tank bump into the alien to knock him off a wall, possibly destroy more aliens in a small chain reaction.
