The remaining defense force has been sent out to try and defeat them. One lucky person gets to fly the latest line of defense ships made: the AX-77 Axelay. However, these ships are still in the prototype stage, and as such, only one exists. So get out there and head to the alien's homeworld. With some luck, you may just be able to take them out at the source...
