Meteoroids

Greetings, New Recruit.
You have been commissioned by the Galactic Federation to destroy meteoroids that are hurdling towards the planet Earth.
Travel into outer space in a Delta S1138 warship and destroy the meteoroids by firing lasers at them.

Good Luck!

P.S. You might want to watch out for GX11 Ships "UFOs" they probably won't be very happy to see you.
