The Walking Dead: All Out War – Prelude to Woodbury Solo Starter SetExpansion

From BoardGameGeek:

The Prelude to Woodbury is a narrative single-player adventure featuring Brian ‘The Governor' Blake and his exploits from before he rose to power in Woodbury and encountered Rick. The introductory quick-start tutorial will take you through the rules step-by-step as you play out the Governor's story, and the box contains everything you need to get right into the action. You do not need the All Out War core set to play, but all of the Prelude to Woodbury components are all fully compatible with the core set, so you can use Brian and his equipment in your larger, two-player games. This set contains 6 unique, collectible miniatures allowing you to add Brian ‘The Governor' Blake to your games, along with 5 Walkers to battle your way through. It also contains an exclusive ‘Solo' version of the game's Event deck.
