A shoot'em up game developed by Cave, known for its high difficulty and dark twist on how machines serve humanity.
1000 years ago, people created war machines to fight for them. However, technology overwhelmed humanity and soon everything was destroyed. To avoid such calamity from happening again, the people who survived sent the war machines to the moon and sealed them there. An eon has passed peacefully, but the war machines showed signs of unrest. To counter their onslaught, the federation amassed their forces and set off for the moon's capitol, Lunapolis.
