Do all the guns have to go to the same shop or what? Also I had bought Dr. Neds Zombie Island and played through the thing but never got the mission "Brains"... Just need to know who I need to talk to or what to do to activate the quest. When I started the level the zombie brains automatically started to drop when I got a crit. 68.22.127.46 18:55, December 5, 2009 (UTC)Genji
