Build and pilot a space ship online. A 2d top down shooter that has endless game play because players can create unique space ships from a collection of space ship modules. Modules include: power generators, power storage, thrusters, cannons, and cockpits. Players create their ships then pilot them in online arenas to see whose design and tactics are the best. No one design rules the battle arena for long as the community is constantly inventing measures and counter measures.
