Necesse is a sandbox survival game with deep crafting, base building, and boss progression. When you play multiplayer, you and your friends build settlements, recruit NPCs, and push through increasingly dangerous biomes together. The problem comes when the person hosting the world is unavailable.

In Necesse, the world save sits on the host’s machine. Without them, nobody else can access it. Your colony, your gear, your NPC settlers - everything is locked behind one player’s availability. For a game designed around long-term progression, this is a serious obstacle.

How SaveSync Keeps Your Colony Running

SaveSync distributes your Necesse world save to every player in the group. Whenever the host finishes a session, SaveSync automatically pushes the latest save to all members. The next time anyone wants to play, they can load the save and host the world themselves.

Your colony keeps growing regardless of who is online.

How to Set Up SaveSync for Necesse

All players in the group need SaveSync installed from Steam. The Necesse SaveSync guide has the exact paths.

  1. Click Necesse in the list on the left. You’ll see Necesse’s save management page.
  2. Click “+ New Save” in the top right.
  3. Select your world from the dialog.
  4. Click “Create Save”. The save starts syncing.
  5. Wait for the green checkmark.
  6. Click the share icon on your save.
  7. Search for your friend’s Steam username and click Share.
  8. Your friend clicks “Activate” on the shared save, which shows as shared by you. The world is ready, they can host it, and it syncs automatically after that.

SaveSync also keeps a full save history: who uploaded which save and when, with the option to revert to any earlier one.

Why Use SaveSync Instead of Dedicated Servers or Manual Transfers

Necesse does support dedicated servers, but running one means paying for hosting or keeping a machine running 24/7. For most friend groups, that is overkill. Manual file sharing through Discord or cloud drives is the other common approach, and it comes with its own headaches:

  • Forgetting to upload. One missed upload means the next player loads outdated progress.
  • File placement errors. Putting the save in the wrong folder means it will not show up in the game, or worse, it overwrites something important.
  • No version control. Two people play at different times, both modify the save, and now you have a conflict with no easy resolution.
  • Dedicated server costs. Monthly hosting fees for a game you play casually with friends add up quickly.

SaveSync gives you the flexibility of peer-to-peer hosting with the reliability of automated synchronization. No server costs, no manual effort.

Want a Dedicated Server Instead? Try the ServerSync Beta

Some groups would rather nobody had to host at all, without paying for hosting or setting a server up by hand.

ServerSync is our second app, built for exactly that. It runs a Necesse dedicated server on a PC you already own:

  • No port forwarding and no config files. Pick Necesse, name the server, launch it.
  • Bring your current world. It converts a local Necesse save you have already played, so nothing is lost moving to a server.
  • Free, with optional premium features. It is in beta now - ask for a key in ServerSync’s Discord.

Build Your Colony Without Boundaries

Necesse rewards long play sessions and steady progression. Losing momentum because your host is unavailable for a few days can derail an entire playthrough. SaveSync removes that bottleneck and lets your group play on their own terms.

Whether you are gearing up for the next boss or expanding your settlement across new islands, SaveSync ensures the save is always ready.
