Not only am I now running three layers of settlement simultaneously, but this new biome has its own distinct challenges. Suddenly I'm in the middle of a tower defence sequence, with swarms of bugs throwing themselves at my miners. It turns out that, like SteamWorld Dig, Build is based around descending ever further through underground biomes, and I've just shovelled my way down into the mushroom-infested swamplands. Though the two layers work quite differently, they're cleverly connected-resources found underground are sent up to the city to fuel further expansion, allowing you to create factories and refineries that produce elements you need to keep mining further out.īut just as I'm starting to think I've got both layers running in harmony… I discover another mine shaft underground, leading to an even deeper level. Keeping all your plates spinning in both places ensures you never run into that boring state of simply waiting for new resources to roll in-there's always something to be fiddling with, whether it's rearranging your residential district above, or sending your miners in search of a hidden door switch below.

It's a wonderfully clever trick, basically giving you two linked games to play simultaneously. Well, you've got to do some digging if you want to find that ancient tech, right? Down here, things work differently-it's a Dungeon Keeper-esque management sim where you dig out rooms rather than plonk down buildings, and explore in search of rare resources and treasures. Early on in the game, you unlock a mine-a full underground map you can switch to at any time. Down here, things work differently-it's a Dungeon Keeper-esque management sim.īut that's just what's happening above ground.
