I enjoyed the hell out of kneeing him in the face and punching the **** out of him. Something so satisfying about the visceral nature of punching a B.O.W.s face in.
Haos is my least favourite boss fight of the whole Chris campaign. That thing is a nightmare because for some reason Chris can't break the shell :/ Only Piers could on my playthrough and the AI was so bad during that time (shooting electricity at the wall) that it made the fight more frustrating than fun.

The chainsaw, it would not die. Ada messes it up a few times, it gets hit by a train, Jake and sherry beat it's ass a few more times, it takes a direct shot through the skull, and finally stays dead when it's body is actually torn to pieces.
Hope the fish that eat the remains don't get infected and turn the ocean wildlife into one big biohazard.
