I don't think I've mentioned this but I am a huge XCOM fan and when i first saw the trailer way back and found out it has become an FPS title , i felt like breaking something. Why change it into a First Person Shooter??! Anyways, nothing can be done and we'll have to live with it some way.
Ok in an FPS point of view, i'm not sure whats unique yet about XCOM. The art I'll say looks good but this trailer shows a bit more gameplay but still not enough information to wow me.
They revealed a release date though. It's coming out on March 9, 2012 on PS3 and Xbox 360.
