Incredible! I hadn't seen this add-on. It's awesome. I didn't play the first one, but the second one is pretty good. So far, everything I've found has been useful for crafting weapons and upgrades. I suppose they've improved this from the first to the second. But like I said, I never played the first one. This game is quite bloody and gory; I'm really satisfied. Hey, and what if co-op makes everything even better? Haha, thanks a lot for your comment.
