Megaman X + Sonic? Starbuster (PC)
"Starbuster is a fast-paced action platformer, inspired by the likes of the Mega Man Zero series, with a focus on faster paced combat, exploration, and weapon customisation. Rocket around, slap things, grab weapons and build your arsenal. After all, while you can't solve every problem with excessive firepower, you can sure as hell solve most of them.
You take control of the experimental android Alpha, the latest weapon built by the ruthless Grey Imperium. This demo focuses on Alpha's escape from the enigmatic Laboratory 19, there's only a small army of Imperial security forces in the way, how bad could it possibly be? Defy your creators, and shoot your way to freedom. Will you succumb to the iron grip of the empire, or will you make it to the stars?"
