Zaga Mission

The situation on planet Zaga 1 is critical. A serious fault has occurred in
the life-support power plant. The citizens count on you to get through the
tunnels that leads to the power plant, and fix the problem.

Zaga Mission is a isometric-viewed action game graphically similar to
Zaxxon. The game takes place underground. You have to navigate your helicopter
through a series of mazes. As if that wasn’t enough the security doors are
opening and closing unpredictably. Hit any of the walls or doors and the
mission is over. Refueling stations can be found along the way, and these are
necessary so you don’t run out of gas.
