Zombicide: Undead or Alive – Running WildExpansion

From BoardGameGeek:

It introduces a whole posse of Survivors that can be either on foot, or riding their trusted horses. But it's not all good news, as this expansion also adds the nightmare of a zombie horse! Each Survivor begins the game on horseback. When they dismount from their horse to enter buildings, their miniatures are swapped and they leave their Lone Horse behind (as a token). While on horseback, the riders gain skills that enhance their movement and increase their chances of a hit. Individual riders have specialized Blue level skills that add to their repertoire while in Rider mode. The Running Wild expansion comes with: 6 Survivor Figures 6 Rider Survivor Figures 1 Abomination Figure 6 Survivor ID Cards 1 Abomination Card 6 Lone Horse Tokens 6 Oversized Color Bases
