I backed this game on Kickstarter and already received my copy of which my friends and I played from 5PM till about 6AM!!! It's a lot of fun. I will give you a overview of changes for those familiar with Zombicide!
-Great character trays to hold your character sheet, inventory and mark your skills! Love it!
-Magic! Combat magic: Acts similar to ranged weapons and enchantments: buffs, movement and things like invisibility! The Mage character is fierce!
-Dragon Bile: Molotov Cocktails however you need to throw the bile and then throw a torch at the bile soaked space to ignite, making a bit harder!
-Fatties spawn alone without a walker escort! But their tends to be more of them!
-Runners get 2 actions, move attack, move move, attack move or attack attack.
-NECROMANCERS: when they enter the board they create a new spawn point which means more zombies, they then attempt to flee to another spawn point, they do not engage the players. If they manage to escape that extra spawn point remains open, if at any point a necromancer escapes and their are 6 spawn points open PLAYERS LOSE!!! However killing a necromancer removes his spawn point and another spawn point of your choice, so you can effectively shut down the spawn points if you work fast and smart! These necro spawn points can open in rooms as well.
