How to Play TMNT Timecrash Expansion for Zombicide White Death with Full Playthrough

About Zombicide: White Death, from BoardGameGeek:

Zombicide: White Death is taking the medieval fantasy setting out into the cold, to the icy lands of a city known as Wintergrad. In addition to the new environment, Zombies, and Survivors, this new installment also brings updated rules and new thrilling mechanics that will send a chill up our spines! Zombicide: White Death is a cooperative game where players face hordes of Zombies controlled by the game itself. Each player controls 1 to 6 Survivors in a fantasy city besieged by Zombies. Once a Quest (a game scenario) has been set, the goal is simply to have fun completing the objectives, surviving and killing as many Zombies as possible! Zombies are slow and predictable, but there are a lot of them. Watch out for their Abomination and Necromancer bosses, too! Survivors use whatever they can get their hands on to kill Zombies. The better the weapon, the higher the body count, but the more Zombies will appear, attracted by the onslaught. Survivors can trade equipment and players can share tactics. Only through cooperation can players achieve victory! Battling Zombies is fun, and Survivors will have a lot to do while exploring the besieged Wintergrad: rescuing fellow Survivors, protecting vital areas, neutralizing dire threats, and much, much more! -description from the publisher
