Lemma

Lemma launched on May 12, 2015 as a complete first-person parkour game. In the weeks following launch, the developer shipped a handful of patches adding features like VR support improvements, new challenge maps, translations, and bug fixes — all through July 2015. The only DLC ever released was the official soundtrack, which shipped on July 8, 2015. After that point, developer activity on Lemma ceased entirely. The developer has since moved on to other projects: a multiplayer alpha for a new game called DECEIVER launched in October 2017, a DECEIVER Kickstarter campaign ran in early 2018, and most recently, on May 20, 2026, the developer announced a brand new game called Ways Unknown — described as a spiritual successor to Lemma — with devlogs on YouTube and a Steam wishlist. None of these announcements reference any new content for Lemma itself. There is no unreleased DLC, no roadmap, no developer statement promising further updates to Lemma. The game launched as a complete product and has been content-complete since the soundtrack released in July 2015.
