Set in a modern day survival-horror universe, the co-operative gameplay of Left 4 Dead casts four "Survivors" in an epic struggle against hordes of swarming zombies and terrifying "Boss Infected" mutants. While
last week the X360 edition of L4D received a client-side fix plugging various cheating exploits, Valve
confirmed that it is working on a patch for the PC version, which has been in the works for a while and turned out to be bigger than anticipated. While no details were revealed as to what exactly it will address, it is expected to be released this week.
