Evaluation
Cosmonator entered Steam Early Access on November 22, 2017 and officially launched on January 21, 2019. During its development and in the period after launch, the developer (Bourbontank) shipped a steady series of updates that added new levels, spells, enemies, and gameplay systems. The last major content update — version 3.3.0, released on December 9, 2019 — added two new levels, multiple new enemies, three new spells, and new Gauntlet content. This represents the most recent substantive content addition to the game.
Since then, the only developer communication has been a maintenance patch on January 17, 2024 (version 4.1.1), which updated the game's engine and fixed some bugs. The developer noted in that post "We're still here and solving any Cosmonator issues that may arise," indicating they remain engaged with the game in a support capacity but have not announced or shipped any new content.
There are no unreleased DLC listings, no announced future content, and no roadmap referencing upcoming additions. The store description does not reference any planned content. The December 9, 2019 content update aligns with the end of a sustained post-launch content cycle. The game appears to have reached its complete state as of that update, with only maintenance support continuing thereafter. No further content has been communicated since December 2019.
Evidence
Version 3.3.0 released: the last known content update, adding 2 new levels, new enemies, 3 new spells, new Gauntlet events, and a boss overhaul. No content updates have followed this release.
Version 4.1.1 maintenance patch: engine update and bug fixes. Developer notes 'We're still here and solving any Cosmonator issues that may arise' — indicates ongoing support but no new content.

About this game
Cosmonator is an 'RPG-em-up': a hybrid of classic fast-paced top-down shmup action infused with deep character building elements.
Slowly build up your ship to suit your particular playing style: perhaps you prefer a passive build that focusses on high firepower, strong sideships, specially customised homing missiles and a drone that fires automatically at any moving enemies? Or a tank build with strong shields, armor, and defensive special abilities? Or a spellcaster with numerous devastating special attacks - and the ability to control time? Each weapon, upgrade, ability and spell in Cosmonator is separately customisable so you can build up exactly the character you want. Add to this a massive level content, including a legion of epic boss battles, and you're guaranteed to keep coming back for more - even after the first playthrough.
FEATURES:
30+ passive upgrades including various firepower and missile upgrades, sideship upgrades, drone upgrades, shield and armor upgrades, and a variety of special feats - allowing you to craft a customised build that suits your desired play style
40+ unique spells that can be upgraded to various strengths; some spells can be augmented to alter their effects in specific ways
40 hand-crafted levels that shape the core of the game
20 extra optional challenge levels
More than 15 epic boss battles
5 difficulty levels, from 'Rookie' to 'Impossible'
An endless roguelike gauntlet mode that continuously increases in difficulty and measures your ability against other players on the leaderboards
Controller support
