OPERATION SERPENS

Operation Serpens launched on July 22, 2020 and received a series of post-launch content updates. The developer shipped four major content releases: a new campaign level ("Kingsnake - Night Patrol") on September 5, 2020; a Zombie Horde Mode on October 29, 2020; and a Co-op Multiplayer update (up to 4 players, new difficulty levels, free locomotion, and drone mechanics) in early December 2021. The December 2021 multiplayer update appears to be the most substantial release and aligns with the features currently described on the store page — all of which are presented as complete, shipping features rather than upcoming ones. Since December 10, 2021, there have been no further developer communications, announcements, or content releases of any kind. The store description makes no mention of planned future content, upcoming DLC, or ongoing development. The developer has not listed any unreleased DLC. The game appears to have reached a complete, finished state with its December 2021 update, and the more than four years of silence since then strongly supports this conclusion.
