Just in case you were thinking Colin McRae Dirt wasn't diverse enough, Codemasters is set to add C.O.R.R races (Championship Off-Road Racing) into the game.
C.O.R.R events throw ten racers, driving different vehicles from buggies to trucks, into a chaotic race around dirt tracks.
With Rally, Hill Climb, Rally Raid, Rally Cross and Crossover events already in there, Dirt could be the most comprehensive rally game ever.
