A new update to No Man's Sky has added in a new 30 hour campaign and rudimentary multiplayer, among other things.

Dubbed Atlas Rises, it is the third major update to the freeform exploration title since it launched a year ago, and the biggest addition so far.

The new central storyline is a branching narrative that allows players to discover more about the universe "and themselves". The fabric of existence is starting to falter, a mysterious new interdimensional race have appeared, and ancient portals have begun to open.

Meanwhile, glitches in the simulation, visualised by strange floating orbs, allow players to see and communicate with up to 16 other travellers and explore the universe together.

"While interaction with others is currently very limited, this is an important first step into the world of synchronous co-op in No Man’s Sky," said Hello Games.

Atlas Rises also introduces a wide array of new and improved features, including much deeper interstellar trading, and overhauled space combat controls, weapons and AI.

Other additions:

Star Systems have varying wealth, conflict and economies
Portals stargates enable quick travel
Terrain manipulation for more complex bases
New farming and mining interactions bring increased depth
Increased biome variety and Rare exotic biomes
Analysis visor & discovery improvements
Galaxy map and many other UI improvements
New S Class ship designs
Low altitude flight and the ability to crash your ship
Crashed Freighters to salvage on planets
Joint exploration

"It’s been a year since No Man’s Sky first released, and it’s been an exciting, intense and emotional time for us at Hello Games,"

"We have been quiet, but we have been listening intently."
