This game is one of the best games i have ever played. The story is amazing the characters are full of...well... character. Bad things out of the way first.
1. As i played the multiplayer it took me forever to find an actual game. So if you have this problem, your not alone, go play the Fantastic Horde mode.
Good things 1.Horde is nothing short of spectacular, it is amazing, up to 5 of your friends get to bash locust skulls together, as the levels get increasingly hard. 2.The story of the game is really good... although it creates more questions then it does answers. but it also has a great sub-stories. and a few surprises. 3 everything else. Pick this game up it is totally worth it.
I got the game today and it has been GREAT! The campaign is super fun and the online multiplayer is just as cool as the campaign. I think one of the new upgrades are that you can use a lot of the guns that are in the campaighn unlike the first one. In the first one you couldn't use some of the amazing guns that are in the campaign. I also think a great upgrade to the game is that in the online multiplayer there are ranks. On the original, I got bored pretty quickly because there is nothing to work towards. Overall I rate this a game a 10! A great game and a MUST buy!
