ETERNAL GUARDIAN RUBINE -The First Fight- is a hair trigger 3D run-and-gun-and-sting inspired by many action games from the 90s, but mainly Sin & Punishment, Alien Soldier, Cannon Spike, and Radiant Silvergun. You as the bio-mechanical superweapon Rubine must use your entire arsenal to blast through various overstimulating levels across multiple small scenarios while racking up the biggest high score you can.
