Stargate: Planetary Defense

The Goa'uld have sent a storm of asteroids hurtling toward Earth in an attempt to obliterate its inhabitants once and for all.

Atlantis, fending off its own Wraith attack, could only spare a single PuddleJumper to counter the Goa'uld assault.

You must blast the asteroids out of the sky before they can enter the atmosphere and wreak havoc on earth below.
