It looks like the developers of No Man's Sky are preparing for an announcement of a new content update. The alternative reality game Waking Titan, which was used to reveal previous big updates and involves websites, phone numbers and radio stations around the world, has entered into a new phase.
The last big update, Atlas Rises, which was released in August 2017 and added narrative content, procedurally-generated missions, and a limited online cooperative mode, was also revealed via Waking Titan.
Members of the ResetEra forum noticed the new phase and are speculating about new possible content for No Man's Sky, speculation which includes a PlayStation VR mode and team-based multiplayer. It's all shrouded in mystery for now, but at least it's a good indication there is more content coming for No Man's Sky as Hello Games continues to flesh out their game.
Thanks, GameRant.
