Evaluation

Arcadium - Space Odyssey launched on January 26, 2026 as a complete game that the developer said would keep growing. Since then the developer has shipped the Endless leaderboards update on March 5, 2026, the mobile version on March 18, 2026, and the Bullet Fest update on June 8, 2026, which added the Victoria and Fauna spaceships, new skills, traits, missions, artifacts, and Russian language support. On January 29, 2026 the developer said Brazilian Portuguese and Japanese localizations were in progress and that more languages would follow, and on February 19, 2026 said more updates were coming. Brazilian Portuguese and Japanese language support has not yet been reported as available. The most recent update to Arcadium itself is dated June 8, 2026. The developer's newest post, dated October 6, 2026, promotes a separate new game called Grazed, with its free demo now out and its full launch set for November 10, 2026. The August 12, 2026 Grazed announcement called Grazed the developer's next project. Because the promised localizations and further updates have not been confirmed as finished, Arcadium is shown as still having content to come, though no date has been set for it.
