Bionic Commando Rearmed 2

Story related, cannot miss.

This is the first boss you'll face. You'll face him at the end of the first level, and be prepared because he has an almost one-hit kill attack if you are too close to him. To beat him you just need to throw your claw at his face, this will make him fall. Then just shoot him, but be careful he will hit you and take half of your HP away when he gets back up. You just need to repeat this until he's dead.
