Polylithic, a Stone Age survival game by polyperfect, launched out of Early Access on August 25, 2026, and is now available on Steam. The full release supports online co-op for up to 10 players, solo play, and Japanese language support, with a 35% discount until September 6.
Polylithic, a Stone Age survival game developed by polyperfect and published by indie.io, moved from Early Access to a full release on August 25, 2026. The launch, covered in Game Spark's weekly indie roundup for the fourth week of July, promised the addition of new systems and content. The final version delivers on that with a concrete set of features: tribal leadership, character customization, hunger and body type systems, hostile tribes, and the option to keep a dog or hyena as a pet.
Co-op is the central pitch, with online play for up to 10 players, alongside a solo mode. The game is now on Steam at 1,600 yen, with a 35% launch discount that runs until September 6. Japanese language support is included, which broadens its accessibility. The two stories trace the same arc: an Early Access survival title preparing its full release, then actually launching with the systems that make its multiplayer promise workable.
