Evaluation
UNDEAD FACTORY: Zombie Pandemic launched on April 16, 2018 as a free-to-play online strategy game. The developer posted two updates in the weeks following launch — one on May 1, 2018 adding Steam Achievements and minor fixes, and another on May 8, 2018 adding Steam Leaderboards. These were the only communications from the developer, and there have been no posts, patches, announcements, or updates of any kind since May 8, 2018. That is the last recorded activity from BTD STUDIO across more than eight years. There is no unreleased DLC, no announced upcoming content, no roadmap, and no developer statements about future plans beyond a brief mention in the May 1 post of future resolution support — which was never followed up on. The game launched as a finished product with no sustained post-launch update pattern established, and the developer has been entirely silent since shortly after release.
Evidence
Steam Leaderboards added — the final developer communication on record, just over three weeks after launch.
Update adding Steam Achievements, minor fixes, and screen resolution adjustment. Developer mentioned planning additional resolution support and Steam Rankings in a future update — both of which were never publicly followed up on beyond the May 8 leaderboard post.
