Shackleton Base: Below. Within. Above. is the expansion that takes the lunar saga to a new level. Imagine this: besides the original base, you can now choose from three different corporations – Lunar City, Undermoon, and Zenith Works – each with its own mission and playstyle. Lunar City wants to attract civilian settlers to the Moon, Undermoon brings an advanced excavation system that lets you dig tunnels beneath existing structures, and Zenith Works offers the chance to collaborate with a construction giant to build shared infrastructure. The game keeps the Worker Placement mechanic, but the most fun part is the variable setup: the board changes every game, so you never play exactly the same thing. Playtime ranges from 60 to 120 minutes, perfect for a board‑gaming night without fatigue. Complexity is medium – easy to learn but with strategic decisions that keep it replayable. Components? Corporation cards, worker tokens, base pieces, and detailed maps. If you love space exploration, sci‑fi, and want something that fits nicely with the base game, this expansion will get you pumped. Just remember: the layout changes, so it’s good to have a little extra time to get used to it, but that only boosts replayability.
