I believe this game got a bad rep starting off their advertising as a spiritual "successor" to Left 4 Dead. I feel like this game would not be as hated as it is if advertised differently. The game is okay at best. It does succeed L4D in terms of gunplay and graphics, but it lacks a lot of the fun substance. It's a shame it fell short because it did seem like it had potential. Some of the boss designs and behavior were really awesome and looked creative. One of my issues is that the difficulty seemed unforgiving. Even on the lowest difficulty, me and my friends would still manage to fail some missions. It didn't seem like we were playing incorrectly so I think some of the difficulty is a bit unreasonable. If you're looking to turn your brain off, it's an okay enough horde shooter to enjoy for a little bit.
