Original Unciv 4.20.1 engine, rules and assets. Browser backend by CobraPi/unciv-web-build, pinned source 6141138e4a9d36bebd142788fd097ae9ceedc690. This independent adaptation is not affiliated with Firaxis or Civilization.
Source code: Mozilla Public License 2.0. Art and audio retain their individual attribution licenses. Fantasy Hex tiles are CC BY 4.0 by CuddlyClover. The Anti-Aircraft Gun UI icon reuses Creative Mania's attributed Artillery icon instead of the ambiguous VectorStock image. Original upstream acknowledgments are retained below.
This release supports single-player with complete native saves in Mindblown storage (account or SDK-managed browser scope). Save game → Save to custom location creates a portable backup; Load game supports import. Native saves are uploaded with revision and identity binding; failures preserve the prior checkpoint and offer an unsaved backup. Legacy device saves require explicit export/import. Original external multiplayer and mod downloads are disabled; Mindblown network multiplayer is not implemented.
