Contributed Hindi language localization to the yairm210/Unciv repository, enabling full UI and gameplay support for Hindi-speaking users. This work involved translating interface elements, updating language files, and integrating diacritics support to ensure accurate representation. Java and Properties files were modified to align with localization requirements, and new flag assets were added for proper language display. Collaborated with team members through co-authored commits to maintain consistency and test coverage, including resolving a localization-related unit test failure. These efforts prepared Unciv for broader adoption in Hindi-speaking markets, expanding accessibility while maintaining release-quality standards in Android game development and localization.
