This game is pretty fun, the story is well done, but the gameplay can be a bit of a pain... You will find most the time when trying to find cover the back to wall mechanic doesn't work, it's not like Gears of War where you need to push a button to take cover this game does it automatically, which can be frustrating...
There has been some false things written about this game on a few reviews, so to correct some people. You can play Multiplayer with a silver account, host your own list server and join list servers, you cannot however join/host RANKED servers as that needs gold subscription... I have been playing the game since it came out, and I'll be honest with you, at the best of time there is no servers online for either, normal or Ranked and I'm a gold account holder, so the insinuation that you must pay £32 for Live is just silly, and would be a waste taking into consideration hardly anyone is playing anyway, the game just isn't being played.
CO-OP I can understand peoples complaints... But obviously don't realise co-op isn't online, it's offline. Yes PC has split-screen, which is why one player needs mouse and keyboard and one a 360 pad, or two 360 pads, which ever you prefer. Obviously this was a developer choice to go split screen and it stinks, especially if you have a small monitor, the other frustration you cannot get a logitech pad to work without editing the registry settings, it does work but is a pain to setup.
When you get co-op going it's pretty fun, it's a whole new story seeing the perspective of Lynch, who throughout many sections of the game is cut off, from Kane seeing his pathological episodes is pretty surreal, but fun!
