Four additional expansions were released in 2007: "Dwarven Battalion", "Scottish Wars", "Goblin Skirmishers", "Goblin Marauders" and "The Hundred Years' War - Crossbows & Polearms". Labelled as specialist-packs, they included new miniatures with unique rules and scenarios. Days of Wonder had planned for the "Heroes of Battlelore" expansion, to be released in 2008 but the expansion was delayed when the game was sold to Fantasy Flight Games. Fantasy Flight Games released the long-delayed "Heroes" expansion in October 2009. It introduced an element of role-play to the game, whereby Heroes gradually grow in power by participating in (and surviving) a series of adventures. Heroes eventually "retire" to become an addition to the player's Battle Council.
