My experience playing this game is great. Having friends playing the game is very interesting and fun, one of the best experience is seeing your friend being outnumber and beaten by a horde of zombie. Sometimes trolling the game by shooting the witch. It is very fun to see your friend have begone berserk by just trolling them. Seeing your friend staring at you for making the game so frustrating while you are just there sitting and laughing for having a great time with them. It is just not about surviving sometimes it's about strengthening your bond and having a good time.
What are your experience playing this game? Have you played with your friend ?
