If you’ve spent hours wandering uncharted planets alone, gathering ferrite dust and dodging aggressive sentinels, you’ve probably wondered how does No Man's Sky co op work to make those adventures way more fun. I still remember my first failed co op attempt: I invited my friend to my session, spent 20 minutes building a small base for us, and then I logged off and he couldn’t access any of it the next day. I had no clue how the hosting rules worked back then, and I wasted so much time because of it. Co op in this game isn’t just joining a server and running around together—it’s designed to let you collaborate on almost every part of your journey, from base builds to community expeditions. But there are a few limitations you’ll want to know before you send that friend invite, so you don’t end up disappointed when you can’t access certain progress together.
How Does No Man’s Sky Co Op Work at Its Core?
At its most basic, No Man’s Sky co op runs on a peer-to-peer hosting system, with no dedicated servers required. When you start a new session, you automatically become the host, and other players can join your instance of the galaxy as long as your network settings allow it. Default settings are set to friends-only, so random players won’t be able to drop into your game without you adjusting the options first. You can have up to 8 players in a standard open world session, and up to 32 players in official expedition events for large group challenges.
Your individual progress never gets overwritten when joining another player’s session, which is one of the best parts of the system. Any resources you collect, missions you complete for your own save, and upgrades you install will stay with you when you leave the host’s game. Crossplay is fully supported across all platforms, so you can play with friends on PC, PlayStation, Xbox, and Switch without extra work, as long as everyone has crossplay enabled in their settings. You can join sessions directly through your platform’s friend list, or use the in-game Nexus station to join random public groups with similar goals.
Key Co Op Features You Can Use With Friends
The co op system lets you collaborate on almost every activity you can do alone, with a few extra shared features that make group play way more rewarding. I’ve used all of these with my regular group, and they turn even the most tedious grinding tasks into a fun time. Here are the most useful features you can take advantage of:
- Build shared bases that all players can access and edit, as long as the host gives building permissions to the group
- Trade resources, crafted items, and even starships with other players in your session, no extra fees or restrictions
- Complete story missions, sentinel pillar fights, and expedition milestones as a team, with rewards for every participating player
- Explore derelict freighters, pirate-controlled systems, and rare biomes together to split valuable rewards evenly
If you’re helping a friend complete a story mission you already finished, you still get rewards like units and nanites, just no story progress for your own save. You can toggle PvP on or off at any time in the network settings, so you don't have to worry about friends blowing up your ship by accident (or on purpose, if that’s the kind of chaotic session you’re going for). You can also mark points of interest for the whole group, so no one gets lost when exploring a large, mountainous planet or sprawling derelict freighter. Last month, my group spent three days building a massive floating base above a radioactive ocean, and we split the work so none of us got burnt out. We even left a landing pad for random public players to stop by and check it out if they wanted.
Common Co Op Limits and How to Work Around Them
No co op system is perfect, and No Man’s Sky has a few limits that trip up new players all the time. The first one I ran into was the hosting rule: if the original host leaves the session, everyone else gets booted back to their own single player game, unless the host manually transfers host privileges to another player before leaving. That’s why I always recommend transferring host rights if you have to log off early, so the rest of the group can keep playing without interruption.
Crossplay players can’t share custom modded content if they’re playing on console, since PC mods don’t work on PlayStation, Xbox, or Switch. If you’re a PC player who uses mods, make sure you disable any gameplay-altering mods before joining a console friend’s session, or you might run into glitches or crashes. You also can’t access your own personal storage containers when you’re on another player’s planet, unless you’ve built your own base computer and storage boxes there first. That’s a common frustration for players who want to bring building supplies to a friend’s base build, so I always recommend carrying all necessary resources in your ship inventory before joining a session.
If you’re playing on Switch, the maximum lobby size is 4 players instead of 8, because of hardware limits. Always sync your save before joining a friend’s session, to avoid losing any progress you made right before logging on. If you want to keep a shared base accessible even when the original host is offline, have every member of the group build a small base computer next to the main build, so anyone can load the area and access it whenever they want. If you're playing with friends on different platforms, make sure everyone has their crossplay setting turned on in the game options. It’s easy to miss, and I’ve spent 20 minutes troubleshooting why my friend on PS5 couldn’t join my PC session before I realized he had crossplay turned off by accident.
Tips for a Smooth No Man’s Sky Co Op Session
After running dozens of co op sessions with my friend group, I’ve picked up a few tricks that eliminate 90% of the usual headaches. First, agree on a goal before you start: are you gathering resources for a massive freighter base, chasing a rare S-class ship, or just messing around and exploring? Having a shared goal keeps everyone on the same page, and avoids situations where half the group wants to grind and the other half wants to race starships around gas giants.
If you're playing with people you don't know well, set your building permissions to "group only" instead of "public" so random players can't destroy your hard work. I once left my base permissions public for an hour, and came back to find a random player had built 10 giant flaming statues outside my front door. It was funny, but it took me 20 minutes to clean up. Use the in-game voice chat or a third party call app if you're working on a complex build or tough fight, since typing out directions takes way too long when a sentinel walker is shooting at you.
Split up roles if you're working on a big project: have one person mine resources, one person craft building parts, one person defend the area from sentinels and hostile fauna, and you'll get the job done three times faster. If you’re doing an expedition together, make sure everyone joins the expedition save before you invite each other. Regular saves and expedition saves are separate, so you can’t join an expedition session from your normal open world save. If you run into a bug where you can't join a friend's session, the fastest fix is usually for both of you to restart your game and make sure you're on the same game version.
At the end of the day, figuring out how does No Man's Sky co op work is way simpler than it seems once you get past the initial setting tweaks and learn the small hidden rules. It’s one of the few multiplayer systems that lets you play exactly how you want, whether you’re looking for a casual group to explore with or a dedicated team to grind for endgame upgrades. You don’t have to follow any strict rules if you don’t want to—some of my favorite co op memories are just me and my friends racing our starships around gas giants for no reason at all. Just keep the small limits and tips we covered in mind, and you’ll have way more fun than you ever did playing alone.
