Perfect
After the minimal disaster story of the first game, the story actually was a good one. The story of Gears of War 2 continues a few months after Gears of War. The Locust have returned and they can sink cities now rather then just pop out of their little emergence holes. It takes a humoris approach at looking into the mind of one of the Gears, Dom. Dom's wife has gone missing and through out the game and Dom tries to find her, adding a new emotional depth to the game that the first didn't have. While this is happening new questions emerge about the Locust's intentions and the whole game takes off from there
For me multiplayer is what makes this game perfect, their are various different game modes to play including Wingman, which is basically you and a partner vs another person and a partner vs another person and a partner etc etc. But there is one problem for me with multiplayer if you dont have anyone to play with you get bots to play with, and if you die, you have a minuscule chance of winning that round. They will look at an enemy and not shoot or just stand around in the open and just wait to be killed. That of course is a small thing and nothing to really worry about.
Another new mode introduced is Horde which is excellent. Horde is a lot of fun with friends and private horde matches can last forever... Horde is basically is just a arcade mode where 50 waves of enemies come after you. The first 10 waves are unique and after that it just repeats the same 10 in a cycle but with different perks to that cycle every time. The game is very challenging even on casual and people will be coming back to it again to try to beat it on Veteran just to get a spot on that leaderboard.
