Background:
In the future, the pathways of space have been taken over by aliens and this has isolated the Federation routeways. The only way to get them back is in a duel to the death. You've been chosen to represent the Federation, its entire hopes rest on your shoulders. You will engage in a series of one on one fights. If you win then you can upgrade your weapons for the next fight, which is advised because each fight gets harder and harder. It's up to you to save the day.
