LFD 2 is imo is one of the best zombie killing co-op experience out there by far. you can play for hours and hours with friends or random strangers and get a kick out of it time and time again. The melee combat is a blast and once you find a M-60, all your zombie killing dreams will come true. And now, in true Valve fashion they have released workshop for Left 4 Dead 2 which is now live. You can find the LFD2 Workshop here. Once you “subscribe” to the items you dig, they will automatically be downloaded to your Steam folder and show up in game for your zombie killing pleasure.
