This game is terrible. It's a game based entirely around Horde mode. It says it's an open world game, but that's just an illusion. Instead, it's a series of corridors connecting one base to another in a series of boring survival shoot outs. Multiplayer is also beyond broken, the server rarely loads properly, and if you manage to find a game, it crashes. I spend 10 bucks on this thing, and then 2 days later, Portal 2 is on sale for 7 bucks... needless to say, I am absolutely livid. I wasted 10 bucks on a terrible game that could have gone to a masterpiece!
