Like many other variants of this game, you manoeuvre a plane over mountainous terrain while bombing or firing your laser at enemy defence installations such as missiles, helicopters, and fuel dumps. You are flying against the clock, and if you survive long enough, you run out of fuel. Destroying fuel dumps does gain you some time, however.

The game increases steadily in difficulty, and after a while the missiles start firing back at you. Eventually you enter caves, requiring some nifty manoeuvring to avoid aliens who are trying to ram your ship. The graphics and sound are very good: and all in all, this is a good example of the type of game. Closer examination reveals that it is identical to the version marketed by Rabbit Software.
