Thing is, people will claim that because there is a MP attached to a game like this that it somehow takes away from the SP experience. Not sure about that myself. UC2 and 3 both had stellar SP experiences. The MP may be 'tacked on' to some but it does not take away from the campaign if their previous games are any indication. Again, ND supported UC3 mp extremely well. Huge updates and patches, modes etc

The nature of this particular game means that co-op online play could be extremely fun, can't wait to try it out myself
