Released in 2020, crafting, base-building, and mining sandbox Hydroneer has been an indie success story that sold upwards of 500,000 copies as of 2022. Now it has a full expansion, Journey to Volcalidus, that dumps a huge new environment to mine and profit from: The island of Volcalidus, which is "over 6 times the size of the original island" and comes complete with a town to rebuild.
The expansion also has a huge new crane truck, a slew of new deep-underground resources to mine, and a bunch of lava-powered machinery that harnesses the island's volcano to get work done a bit easier. There are also new systems around augmenting your tools and machines for extra effect while crafting them.
