The stand alone game for the PS3. Cheapest price I could find so I've bought it.
Edit: I have just checked and the price on the site is now £20.49! So it's droped by £4.50 since saturday!! Bit crap for me but good for any other bargin hunters.
(Anyone know if CD-WOW will give me the difference? :P)
