From the Publisher:The Asteroid Rebellion is slowly being crushed by the forces of Terra. In a desperate bid for survival, the rebels outfit an asteroid with heavy weapons -- including the secret gravity warper -- and send it on an earth-grazing orbit. The Terran fleet comes out to do battle with Star Fist.From the Designer:This is an intermediate-level game...not exactly beer-and-pretzels, but not difficult. It's definitely tactical rather than strategic the best-laid plans can fall apart very quickly when your foe gets a lucky hit on a vital system.Movement system based on Triplanetary, by Marc Miller Cover by Alan Gutierrez back cover by Ruth Thompson Map and counter graphics by Carl Anderson and Manuel Garcia - BoardGameGeek
