from what i gather it has only the name to do with shadowrun and some very loose "class" situations, the rest is all fps with too few maps to make it worth buying.
I was looking at it today at Fry's and even if I was of the mind to buy it I wouldn't be able to play. Requiring Vista in order to play a new game is marketing genius which by definition is fucking evil.
