Wrecker

You are in command of an elite force of soldiers tasked with defending the Earth from a seemingly never ending horde of alien creatures.  Only you and your comrades in arms stand between Earth and total annihilation!  Your job is merely to survive as long as possible, hold your ground, and never, EVER GIVE UP!

Use your T-9000 Tesla Torpedo Cannon to destroy the enemy spacecraft.   Use skill, timing, and tenacity, but don't lose your focus as it only takes one hit to end you and leave a hole in Earth's defense shield.
