The 3.3 update for No Man's Sky called Expeditions introduces a new game mode that will change every season. The multiplayer mode lets players explore a planet together and reach milestones, to foster a sense of community and welcome in new players.

The Expeditions mode is distinct from the existing Normal, Creative, Survival, and Permadeath modes, and Hello Games promises that each season will introduce new adventures for the community to explore together. In Expeditions, all players start on the same planet, and completing missions will unlock mission patches to display. You'll also get cosmetic rewards that you can take back into the other game modes, like a new jetpack, exclusive ship, weapon, and title already available.

The Expeditions also includes some tweaks to the overall game as well. A Target Sweep mode expands your exploration options with new survey techniques, and missions have been overhauled to include the Target Sweep mechanic. Space Station missions have gotten an overhaul with greater rewards for higher-level missions. The UI and HUD have been overhauled as well, and Hello has made changes to early game balance and building instructions as well as bug fixes.
