Terra I is responsible for supplying Zenbar crystals to Earth, which provides 72% of Earth’s power. However, the defense systems controlled by the computer have been sabotaged, and space pirates are nearby. Your mission is to pilot the F-117 Starwarrior to Terra I and eliminate any threats that come your way.
Your ship can move in four directions: up, down, left, and right. Initially, you will have a top-down view of the F-117, facing downwards. You must shoot meteors and space pirates as they approach from the bottom of the screen. After clearing this section, you will switch to a side view of the ship and face left or right. Robot interceptors will emerge from the sides and must be eliminated. Next, fish force fields (yes, fish force fields) will appear from the top, moving downwards, and you must destroy the fish-shaped devices. These force fields are Terra I’s final line of defense, and once you have overcome them, you will have accomplished your mission.
In the two-player mode, player one controls the left and right movements of the F-117, while player two controls the up and down movements. Firing alternates between both players every two seconds, so they must collaborate to succeed.
