You are in the middle of space alone -- or are you? Suddenly an army of aliens appears. They can't be this far out in space unless...you guessed...these monsters are planning an attack on our solar system. You fight your way through the first wave of evil and sink, exhausted, into your sear. Then a warning signal flashes on...more aliens? It's the enemy's Mother Ship. Who is going to save us from the swarm of hideous creatures? You are!
