Evaluation
SpaceChem launched on March 2, 2011 and received one DLC — the 63 Corvi Mission pack — on July 22, 2011. That is the only paid content ever released for the game. Over the years, Zachtronics continued to maintain SpaceChem with bug fixes and a community-driven feature update in February 2019, but no new story content or expansions were ever announced or released beyond the original DLC.
The most significant signal comes from a July 5, 2022 developer post announcing Last Call BBS as "the last game from Zachtronics," explicitly marking the studio's retirement. This confirms that no further content will come from the developer for any of their games, including SpaceChem. The game has been complete since the 63 Corvi Mission DLC shipped in July 2011, and the studio that made it has since closed.
