Zaga Mission

Zaga Mission is a Commodore 64 action game published in 1984 by Kingsoft and Anirog. It uses an isometric view with a diagonally scrolling playfield, and puts the player in a helicopter flying through underground mazes on the planet Zaga 1 towards a power plant. Collision rather than enemy fire is the main threat: touching a wall, or one of the security doors that open and close unpredictably, ends the mission at once, and refuelling stations have to be reached along the route to avoid running out of fuel.
