What is happening now
Cosmos is a 1981 arcade shooter, though recent coverage indicates significant confusion around the title's identity. No Man's Sky developer Hello Games has announced an upcoming update called Cosmos to coincide with the game's tenth anniversary in August, maintaining the studio's approach of free post-launch content. Details on the update remain limited, though it's been teased as part of the ongoing development cycle that has defined No Man's Sky since its contentious launch. Separately, the coverage also references Stellar Odyssey, an unrelated idle RPG with MMORPG elements focused on space exploration, suggesting "cosmos" as a thematic reference point across multiple contemporary titles.
