Been co-oping through all the co-opable games on PS+ in alphabetical order with a buddy of mine. We got to this one two weeks ago and I figured it would be a pop in, play for an hour, and then move on but now we've played 20+ hours of it over multiple days. This game is wildly fun........for a bit. It's starting to get a bit too grindy now that we're on level 42 out of 89. In the beginning they're constantly throwing new enemies at you and there's lots of different types of weapons constantly unlocking. But now at Level 42 everything is too chaotic you're pretty much limited to only using your best guns to make it through. I'd still recommend playing it though if you've got a co-op partner to play with.
