You are the Rocket Zomby flying through space to recon earth. Try your best to rocket through the galaxy avoiding all that stands in your way and the entire Live human population of earth.
You are the first. So, lead your zomby brothers and sisters through space to gobble up some more good eats.
Watch out, though. They will use their technology against your invasion. Death rays and rockets alike will speed toward you with one goal in mind: stop the zomby.
It is your job to keep going long enough, so that your friends can follow you. Along the way, eat as many brains as you can; they will give you extra chances as you fall victim the the zomby killing weapons of earth.
So, Good Luck and Rocket On!
