The Surge (PC) GOG Key GLOBAL

In The Surge, you will play as the unluckiest guy ever. He starts working at CREO, a corporation which claims to be saving the world. Unfortunately, you get knocked out on the first day and wake up in a cool exoskeleton after the complex you were working at gets hit by a catastrophe.

From then on, you will have to fight for survival, defeating enemies and chopping off the parts you want to use for improving your own exo-gear.
