Left 4 Dead is now 50% off to coincide with the release of the new download content “Crash Course.”  This scenario connects the events between “No Mercy” helicopter rescue and “Death Toll” beginning.  I have greatly enjoyed this game on 360 but the lack of user mod community really sucks.  I recently upgraded my PC and will be biting on this $15.00 dollar purchase.  Here I come mall from Dawn of The Dead.
