Three Codemasters racing titles have been removed from Steam.
DiRT 3, F1 2013 and GRID have all vanished from Valve's platform with no reason given for their disappearance. This comes mere days after the same three games were taken off of GOG.com for licensing reasons, one can only only assume the same applies to the Steam versions too.
Those of you that already own the Steam versions of DiRT 3, F1 2013 and GRID will be able to download and play as usual. However those looking to purchase any of the three titles are currently out of luck and at this point it's anyone's guess as to when they will reappear (if at all) back on Steam.
We'll keep you up to date as soon as we know more.
