Secret Quest

It started with one station, then three, then eight. If something isn't done, the aliens will overrun Earth. It is up to you to destroy the stations by setting their self destructs. You move from room to room, fighting any enemies you encounter. When you beat an enemy, you get an energy pod or oxygen bottle. Fighting aliens depletes you energy and/or oxygen so kill quickly. Each weapon inflicts different damage, and depletes a different amount of energy.
