In Defense Grid: The Board Game, a co-operative deck-building game based on the Defense Grid video game franchise, you and your fellow players must face off against waves and waves of aliens as you try to #ProtectTheCores. How you construct your deck for each mission is just as important as where you place your towers and which ones you choose to power each round. Reclamation of Atavio is a Defense Grid: The Board Game campaign expansion consisting of 24 individual scenarios that are narratively and mechanically linked. The scenarios feature a couple of new mechanisms, such as tower unlocks, individual card rewards, Boss-Aliens, and specific map rules, in addition to narration from iconic characters of the computer game such as Fletcher, Cai, Rissler, and others in a novel (non-canon) tale within the lore of Defense Grid.
