Ahhh, the best zombie shooting games, full with intense and requires great teamwork, and all the freaking bloody zombies around. I can't actually stop playing it, repeating campaign with even harder difficulty. Besides, vast workshop collections just enhanced the gaming experience to a whole new level.
But, I haven't actually see people over here mentioning it, maybe it's popularity is fading away by period of time. But I still like it and some people are still playing it.
Do you still playing the game?
