Campaign is so awful that it'd be better if they just didn't have it. Multiplayer was pretty fun, actually. The 10 attachment system was so goofy and insane but it actually balanced the guns a lot and made almost all the weapons viable. It was actually alright. The zombies mode was fun for a little, I liked that they tried something different for the first map but when the next one came out it just fell to pieces. It was the exact same thing and it just straight up sucked. Overall, this game deserves the reputation it gets for being trash.
