This is a 3D remake of the 1981 Intellivision game of the same name. Fend off the attacking saucers long enough to destroy the five missile silos and destroy the Alien Station. Save the Earth!!!

The Alien Station threatens the Earth, and you(well, you
and your ship)are the only one who stand between it and
Earth's total destruction. Avoid the marauding saucer
defenders long enough to knock out the station's five missile silos before the Earth moves into target position, and put the station out of commission once and for all!

Controls:

ARROWS - Move the ship around
SPACE - Fire ship's lasers
B - Drop a bomb (used to destroy silos)
A - Hold to accelerate
Z - Hold to decelerate
ESC - Quit
P - Pause game, press again to resume

Avoid slamming into the trench floor or walls. You've only got ONE ship!!
