No Man's Sky Swarm Update (6.4): Everything New, Patch Trail & New Terms

The Swarm was 2026’s combat update: version 6.4, released in May, it filled ordinary space flights with coordinated enemy fleets, let you capture the pirate freighters you beat, and ran a three-team community war through Expedition 22. It was also the game’s biggest space-combat rework in years — and the community’s verdict was unusually consistent: the battles are the best large-scale space combat No Man’s Sky has ever delivered.

Last updated: September 2, 2026, current through patch 6.45.1 and the staged Cosmos rollout. This page is the update hub: what 6.4 added, the new terms it introduced, the expedition that shipped with it, and every patch since. For the fight-by-fight mechanics, jump to the swarm battles guide; for the year in updates, the 2026 update tracker covers everything around it.

What the Swarm Update Added

Four things define 6.4:

• Swarmer ambushes. Coordinated enemy ships now ambush routine flights — not set-piece missions, the regular game. Flying unupgraded through unclaimed space became genuinely dangerous overnight, which is exactly the pressure the update wanted.
• Fleet-scale space combat. The fighting is sustained and large-scale, with your freighter summonable into the fray. Community reaction called it the best large-scale space combat in the game’s history.
• Boardable pirate freighters. Beat a pirate freighter and you can now board it, then either demand control (take the hull for yourself) or demand tribute (cargo and units). It is the cheapest route to a freighter in the game — the capture walkthrough covers the full loop and its traps.
• Expedition 22. The seasonal expedition shipped with the update and turned its themes into an eight-week, three-team war with the Hive of Glass as the finale.

The New Vocabulary, Defined

The update introduced its own lexicon. If a patch note, a milestone, or another player uses one of these, here is what it means:

Term	What it is
Swarmer / swarm ship	The coordinated enemy fighters that ambush routine flights in numbers
Boarding	Docking a beaten pirate freighter to claim it, instead of destroying it
Demand control	The boarding choice that takes the ship itself as yours
Demand tribute	The boarding choice that takes cargo and units and leaves the hull
Pirate frigates	Mercenary escort ships — hiring them before a capture stops the enemy fleet fleeing
Hive of Glass	Expedition 22’s finale encounter, the community war’s closing fight
Insectoid Armor set	Expedition 22’s signature cosmetic reward, styled after the Swarm’s chitin-and-glass enemies

The deep mechanics behind the first five live in the swarm battles guide; the expedition terms are broken down on the Expedition 22 page.

Expedition 22: The Three-Team War

Expedition 22 ran May 27 to July 19, 2026 — about eight weeks — and it played the update’s fiction straight: three player teams fought a community war across the milestones, with the Hive of Glass encounter as the closing set-piece. Rewards followed the insect theme: the Insectoid Armor set as the signature cosmetic, the Swarm expedition decal, and the usual per-phase cosmetics and titles.

The window is closed, but the content is not gone. Past expeditions stay replayable from the expedition terminal on the Space Anomaly on any save, rewards are account-wide once unlocked, and Hello Games’ fall Redux tradition means a Swarm re-run is expected around late October. The Expedition 22 page has the full reward list and both replay routes.

The Patch Trail: 6.4 to 6.45.1

The Swarm shipped as 6.4 in May 2026 and was followed by six patches on a steady cadence:

• 6.41, 6.42 (May) — the first wave of fixes after launch
• 6.43, 6.44, 6.45 (June) — the June stabilization run
• 6.45.1 (June 22, 2026) — the update’s final stable patch, and the version the whole 6.4 family settled on

Practical takeaway: if you played at launch and bounced off a rough edge, 6.45.1 is the version to judge the update by. The recent updates page keeps the full timeline with every patch listed.

What Came After the Swarm

The next update was the big one: Cosmos (6.50), the tenth-anniversary update announced on August 9, 2026, is rolling out in stages — free interstellar flight between star systems, and landing on stars with new heat-resistant gear. Our Cosmos update guide tracks every confirmed detail, and the 2026 update tracker puts Remnant, Xeno Arena, The Swarm, and Cosmos side by side.
