No Man’s Sky just hit its 10th birthday, and the number everyone’s talking about isn’t a sales figure or a review score — it’s this: after a decade and millions of players, less than 1% of the game’s planets have ever been visited. Hello Games picked this exact moment to tease something new called COSMOS.

What happened

Hello Games marked the anniversary by reminding everyone just how absurdly big No Man’s Sky still is. Despite a huge, dedicated community logging thousands of hours between free content updates, the procedurally generated universe is so massive that human exploration barely makes a dent in it. Alongside the celebration, the studio dropped a tease for COSMOS, without piling on extra detail, which is very on-brand for a team that’s learned to let updates speak for themselves after the game’s rocky 2016 launch.

Why it matters

The “1% explored” stat isn’t just a fun trivia line, it’s basically the whole pitch of No Man’s Sky proven true a decade later. This is a game built on procedural generation at a scale most studios wouldn’t dare attempt, and the fact that it’s still technically unfinished by players — in the sense that there’s always more out there — is exactly why people keep coming back. It also says a lot about Hello Games’ approach: instead of padding the game with premium DLC, they’ve spent ten years dropping free major updates that keep giving explorers new reasons to jump back into the ship. That’s a rare thing in live-service gaming, and it’s a big part of why the community has stayed loyal.

What to expect

Details on COSMOS are still thin, but given Hello Games’ track record, expect it to slot into the same pattern as past updates like Fractal, Echoes, or Orbital: a free addition that reshapes some core system rather than just tacking on cosmetics. With the game already running across PC, PlayStation, Xbox, and Nintendo Switch, and presumably positioned well for Nintendo Switch 2, a splashy update timed to a 10-year anniversary feels like it’s meant to pull in both longtime explorers and newcomers curious about what all the fuss is about.

Ten years in and No Man’s Sky still hasn’t run out of universe to show people, which is a genuinely wild thing to be able to say about any game. If COSMOS keeps up the studio’s habit of turning “we promised big things at launch” into “we actually delivered them eventually,” this anniversary update is worth keeping an eye on.
