I'm really going to need to set aside some time to play through lots more of Core Keeper - because they keep rolling out some excellent updates to it.

What is Core Keeper? You get to explore a vast cavern of creatures, relics and resources in a mining sandbox adventure for 1-8 players. Mine, build, fight, craft and farm - a bit like a top-down Terraria in a way.

Riders of the Underground was announced as the next major free update for the game bringing in new features like cute rideable mounts along with new pets and a new biome to explore.They also said they're adding in 10 new armour pieces, 15 new rings, 15 new necklaces, new pouches, new enemies, and new weapons - so quite a lot then. There's already plenty of content you can put lots and lots of hours into and now it's just bigger again!
