TETRA is forced to re-enter the atmosphere and begin the fight for human survival.
STRATEGIC SHOOTING GAME
Stages with various topography such as intricate gaps and moving containers become battlefields, and enemies attack from all directions, up, down, left and right. And 23 bosses await beyond... 6 highly challenging stages await you.
There is a chain bonus that keeps increasing the score by continuously defeating the same enemy, a secret bonus generated by defeating enemies in a specific order, and a hidden score item.
