Killbot

Killbot launched on July 10, 2016 as a cooperative online zombie shooter. The developer's entire post-launch communication history spans only a few months: a new mission was added on November 2, 2016, trading cards were added on November 15, 2016, and a hat bug was fixed on December 9, 2016. There have been no developer communications of any kind since December 9, 2016 — nearly a decade of silence. No future content was ever announced, no roadmap was published, and there are no unreleased DLC listings on the store. Given that the last developer activity was on December 9, 2016 and no content or updates have followed in the years since, the game is best understood as having reached the end of its development cycle at that point.
