\"Players<\/p>\n

To join a friend’s world in Core Keeper multiplayer<\/strong>, ask the host for their Game ID<\/strong>, choose Join Game<\/strong> on the main menu and paste it in. Up to 8 players<\/strong> can play together on PC, PlayStation and Xbox (4 on Nintendo Switch), but crossplay only works between PC stores and within the same console family. Here’s the full step-by-step, plus the limits and fixes worth knowing.<\/p>\n

Good timing:<\/strong> Core Keeper has a free weekend on Steam from Thursday 8 October to Monday 12 October<\/strong>, with the full game and online multiplayer, so friends can join you without buying it first. If they keep playing afterwards, their save stays in their library.<\/p>\n

How do you host a Core Keeper multiplayer game?<\/h2>\n
    \n
  1. Start or load the world you want to play in.<\/li>\n
  2. Press Esc<\/strong> (or open the pause menu) once you’re in the world.<\/li>\n
  3. In the top-left corner, choose Copy Game ID<\/strong>.<\/li>\n
  4. Send the Game ID to your friends.<\/li>\n<\/ol>\n

    Your friends can only join while you’re in the world, unless you run a dedicated server. Anyone with the ID can join, so only share it with people you want in your world. If you need a new ID, you can change it from the same menu.<\/p>\n

    How do you join a friend’s world in Core Keeper?<\/h2>\n
      \n
    1. On the main menu, choose Join Game<\/strong>.<\/li>\n
    2. Paste the host’s ID into the Enter Game ID<\/strong> field.<\/li>\n
    3. Press Join<\/strong> and pick or create the character you want to play.<\/li>\n<\/ol>\n

      On Steam you can also skip the ID: if you’re Steam friends with the host and they’re online, they can invite you straight from the Steam friends list.<\/p>\n

      Does Core Keeper have crossplay?<\/h2>\n

      Partly. Fireshine Games, the publisher, says Core Keeper “ONLY supports cross-play between PC platforms”<\/strong>, using its PlayFab networking, so Steam players can join players on other PC stores. Consoles can play within their own family: PS5 with PS4<\/strong>, and Xbox Series X|S with Xbox One<\/strong>. PC and consoles can’t play together, and Fireshine says there are currently no plans to add PC-to-console crossplay.<\/p>\n

      If you’re on PC and your friend bought the game on a different store, both of you need to turn on cross-play in the gameplay settings<\/strong>, or you won’t be able to connect.<\/p>\n

      How many players can play Core Keeper together?<\/h2>\n

      Up to 8 players<\/strong> on PC, PS5, PS4, Xbox Series X|S and Xbox One, and up to 4 players<\/strong> on Nintendo Switch. Pugstorm says the difficulty scales depending on whether you’re playing solo or as a team, so bigger groups face tougher enemies.<\/p>\n
