Alien Attack

You await your doom inside the crippled space station. The aliens will be attacking in clusters. There are eight different ways that they can get in. When they do come, the station's force shields will protect you from at least three blasts on each side. Then, if you're lucky, you will figure out how to operate the malfunctioning laser cannon and fight back.

Maybe by destroying enough attackers you will be able to recharge your shield and save the space station and your life.
