Mission Attack

Mission Attack is a 3D science-fiction themed shoot-em-up. Your goal is to attack and destroy the enemy's tower after passing through four waves of opponents. Each wave takes place in a different geometric landscape, with enemy craft arriving from the distance, and trying to collide with you. You can move backwards and forwards along the bottom of the screen to target or avoid the enemy. Every time you move, your energy depletes but shooting the orange enemies replenishes your fuel.

The game's four zones are the black zone, the blue zone, the space base zone and the mother tower zone. The main difference between these is the background graphics. The blue zone is slightly different in that you head towards distant mountains along a narrow path and straying from the path uses a lot of energy. Enemy bikers may suddenly appear in the last three zones, but are missing from the first. The last zone ends when you reach and destroy the tower, after which you then start from the beginning at a higher level of difficulty.
