Lazy Galaxy: Rebel Story

An old robot named H-34-RT wakes up in a derelict space station orbiting his home planet. His civilization was destroyed long ago by evil O'Xelg, but he has yet to figure that out. After an initial shock, he decides to follow his old defense routines: that means fighting the invaders, even if he is alone now.  Lazy Galaxy: Rebel Story is a challenging, squad-based shoot-em-up/bullet hell roguelite. Fly through tons of bullets, defeat various enemies and engage challenging bosses, all this to help a lonely robot complete his mission.  Features:  Start out alone, but rescue allies as you progress  Your allies do not level up by killing enemies. Rather they get stronger once they get to know you and each other better  Change you fleet formation to avoid bullets and focus fire  Use your ally special abilities to boost your firepower or heal yourself  2 Player Local Co-Op Support  Fly through eight different levels, encountering various enemies and fighting your way to the O'Xelg communication base Inspired by Steredenn and Jets'n'Guns Gold, the game tries to add its own distinguishable traits to the genre.
