Game Picks | Can't Stop Digging: Core Keeper 1.0 Co-op Progression and Persistent Servers

Core Keeper reaches its 1.0 release! Explore The Passage's endgame obsidian biome, Mage and Summoner combat paths, co-op roles, and direct-connect dedicated server setup.

Anyone who has played Core Keeper, known to Chinese players under several localized titles, knows how addictive it can be! You promise “one more swing of the pickaxe before bed,” follow a trail of glowing fungi, and before you know it you have laid minecart tracks, automated power grids, and dozens of automated fields while dawn breaks outside. The game has now reached its milestone 1.0 release! It adds The Passage, a dark endgame biome beyond the boundary, introduces exciting Mage and Summoner combat paths, and fully supports direct IP multiplayer. Get your old mining crew together: it is time to dig your way through the underground world again!

Core Keeper 1.0 release

What New Co-op Activities Stand Out in 1.0?

  1. The Passage endgame biome and obsidian technology: This dark endgame zone deep within the Sunken Sea is filled with unknown primordial creatures. Gather rare Pandora ore to craft the game's highest-tier obsidian armor, automated smelting equipment, and exceptional accessories for even more satisfying combat!
  2. Mage and Summoner paths: no more all-melee squads: The combat-specialization system has been reworked with mana and summon slots. One teammate can cast fireballs with a staff from afar or slow enemies with frost storms; another can become a necromancer and send skeletons and little ghosts to surround the boss. The opportunities for squad coordination grow dramatically.
  3. Relaxing ways to spend time together: One player explores underground and reveals the map, another digs ponds near the base to catch rare fish, and a third prepares feasts that boost movement speed and attack. Whether you want challenging combat or a laid-back life, there is something enjoyable for you.

Why Use a Dedicated Server?

Crop growth, livestock breeding, and automated drilling all depend on time passing in Core Keeper. If a player's personal computer hosts the session, the whole underground world freezes when the host leaves. A dedicated server running 24 hours a day lets whoever finishes work first log in to harvest crops or add coal:

  • Server AppID: 1007 (embedded in the client tool) or 1963720 (Dedicated Server)
  • Core communication ports: UDP 27015 (main communication port) and UDP 27016 (query port)
  • Complete setup guide: For world seeds and networking settings, see Core Keeper Dedicated Server Setup and Configuration Guide.

An Easier Way to Manage Your Squad's Server

We recommend our open-source LanGame Server Manager (LGSM) (GitHub: SZSLGJCOM/LanGame-Server-Manager). Its Core Keeper one-click deployment preset supports Direct Connect IP settings and unobtrusive automatic backups, preventing network instability or unexpected crashes from wiping out your excavation progress.

Playing Across Networks and Joining the Server

  • With a public IP: Forward ports 27015/27016 on your router. Friends can select “Join via IP” from the main menu and enter public-IP:27015 to arrive at the core camp.
  • Without a public IP on rental networks or behind multiple NAT layers: Open the LINK virtual LAN feature in LanGame OS Orbit together, create a private room, and connect directly using the generated virtual network adapter IP. The high-speed encrypted P2P tunnel offers zero-latency underground multiplayer!
