Evaluation
Diluvion originally launched on February 2, 2017. Over the following year and a half, Arachnid Games continued developing a substantial overhaul called "Resubmerged," which launched as the default version of the game on September 28, 2018. This update was a ground-up rebuild featuring a completely revised salvage system, ship upgrade system, UI, new side quests, improved AI, and more.
Following the Resubmerged launch, the developer went quiet for an extended period before returning on March 17, 2024 with a maintenance patch (version 1.3) that fixed quest breaks, save file issues, inventory problems, and added controller support. The post noted that the team had been spending "bits of free time here and there" over the prior two years to address lingering issues — suggesting this was a goodwill maintenance effort rather than the start of a new content cycle.
All five DLC items (soundtrack, artbook, pre-order sub, special edition sub, and captain's journal) were released on the original launch date of February 2, 2017, and none are listed as unreleased. The developer has made no announcements of future content, roadmaps, or expansions at any point since the Resubmerged launch in 2018. The March 2024 patch was a bug-fix release with no content additions, and there have been no communications from the studio since that date.
The game launched as a complete narrative experience, received one major overhaul (Resubmerged), and has since received only maintenance support. With no outstanding commitments, no unreleased DLC, and no developer statements pointing to future content, the game is complete. The most recent meaningful content milestone was the Resubmerged launch on September 28, 2018, though the final developer communication was the March 17, 2024 maintenance patch.
