Wow! If this isn't the coolest game there is, then someone needs to step up and enlighten me. I am absolutely blown away by the graphics, game play and co-op! Unbelievable!!! The graphics rival Oblivion in lush quality and detail (though I still think Oblivion is the best looking game ever, hence the independently moving foliage). The unique style of gameplay and the need for cover make it very interesting, very un-halo-like (run and gunners beware) and more realistic. The co-op is amazingly diverse, with the ability to start a campaign, invite your friends to join you or have a friend over to play split screen and you never lose a beat. The ability to seamlessly switch is something I've never seen. Also, the online multiplayer plays and moves exactly like the campaign, plus I've noticed very little lag. I played last night with EPICCliffyB (the game's lead designer) and was treated to the knowledge that three more significantly larger and lusher multiplayer maps will be added to the Xbox Live marketplace by the first of the year. Hell, yeah! All in all, it is the best game I have ever played and would highly recommend it to everyone. :)
