A shared cave to dig through together
You wake up in a forgotten cavern and start digging outward from the Core. One of you mines ore while another clears monsters, then you meet back up when someone finds Clay Caves, crystal caverns, or water that needs a bridge or a boat.
The world supports 2-8 player drop-in/drop-out online co-op, plus dedicated servers, so co-op friends can come and go without ending the run. Exploring at your own pace is the point: scan for Titans, clear ruins, trade with merchants, and keep pushing into new biomes.
Split the chores, share the loot
There is always another job to hand off. You upgrade pickaxes, shovels, fishing rods, bombs, and mortars, level up mining, combat, cooking, and farming skills, and spend talent points to shape your abilities. Someone automates smelting and storage while someone else plants a garden.
Combat builds around choice too, with melee, ranged, magic, and summoning styles, armor sets, and rare Titan loot to pass around. You find a weapon upgrade, toss it to the friend it suits, and keep moving deeper.
Build a base that fits everyone
Your base is the meeting point between trips. You place walls, furniture, lights, farms, animal pens, and crafting stations, then reshape it from a practical mining outpost into something cozier. Custom outfits and character looks help tell each other apart in the dark.
It is useful as well as decorative: cook recipes for healing food, smelt ore, store gems, hatch pets that fight beside you, and lay rails to speed up return trips. One friend designs the kitchen, another builds the boss arena. Both are correct.
Titans give you a reason to team up
The big milestones are legendary Titans, each tied to the secrets of this underground world. You prepare gear, cook buffs, set traps, clear ground for the fight, and take them on together. Winning powers up the Core and opens the next stretch of cavern, from the Sunken Sea to the Desert of Beginnings.
Between bosses there is plenty of low-pressure time: fish in strange waters, tend crops, raise animals, meet the Cavelings, celebrate the seasons, and play music on playable instruments. Good for groups that like a fight followed by a long, chatty wind-down.
Good to know before you dig in?
How does co-op actually work?
It is built for 2-8 player drop-in/drop-out online co-op, with dedicated servers if one friend hosts the world. That makes it simple to explore together, split tasks like mining, farming, and building, or wander off alone and regroup at the base.
What do we do together most of the time?
Mine resources, upgrade tools and armor, build and automate your base, and explore biomes to find and fight Titans. Around that core loop you can garden, fish, cook recipes, care for animals, hatch combat pets, trade with merchants, and sail or ride rails to new areas.
Is it cozy or challenging?
Both, depending on how you play. Farming, building, fishing, and decorating lean relaxed and wholesome, while Titans, mini-bosses, and deeper biomes ask for better gear, food buffs, and some planning. Groups can spend one evening decorating and the next preparing for a boss.
Can I play solo too?
Yes. The same world supports solo play, so you can keep digging, farming, and preparing your base between co-op sessions, then have friends join back in when everyone is online.
