Far more fun than I thought it would ever be. It took me 10 or so hours to really start enjoying it. The combination of the human enemies and the Freakers, who are so fun to hunt, snuck up on me.
The characters are interesting and the story is engaging. But fight the Freakers is where the money is.
I recommend spending your time doing the side tasks, upgrading your bike and weapons. It really pays off, and makes the game much easier.
I avoided buying this game until it was half price. I delayed playing this game for weeks. I am happy I put some time into it.
