The two-person European studio’s dieselpunk artillery game converts its 700,000 wishlists into one of August 2026’s strongest indie launches
This coverage previewed Iron Nest: Heavy Turret Simulator in July, at the time noting 570,000 demo players, 700,000 wishlists, and 6,000 demo reviews as remarkable pre-launch signals for a dieselpunk artillery simulator built by two developers. The August 6 launch has now validated those signals decisively.
First-weekend results from Nick Talmers and Dominic Ratos’s two-person studio: 300,000+ players have played the game since launch. Steam reviews stand at 5,306 with 98% Overwhelmingly Positive — up from the already-strong demo baseline. Peak concurrent users hit 17,599. The game is holding a consistent top 5 position in Steam’s global best-sellers chart.
What the Numbers Mean
The conversion from 700,000 wishlists to 300,000 first-weekend players is a healthy ratio that indicates the wishlists represented genuine purchase intent rather than speculative interest. Many games with large wishlist counts fail to convert those into proportional sales — the wishlist becomes an optimistic artifact of a demo moment rather than a purchase signal. Iron Nest‘s first-weekend numbers suggest the 700,000 who wishlisted were largely players who specifically wanted to own this game, not just players who thought it might be interesting.
The 98% Overwhelmingly Positive rating from 5,306 reviews is the number that matters most for long-term commercial health. Games hold this category threshold for their entire lifetime — a launch-week Overwhelmingly Positive rating tends to sustain as the player community grows, because the audience that formed in the first days was enthusiastic and the players who discover the game later tend to include even more precisely interested players (those who heard about it through word-of-mouth from people who loved it) rather than speculative purchasers.
Peak concurrent of 17,599 places Iron Nest in the tier of mid-sized successful indie launches — not in the stratosphere of viral phenomena, but solidly in the range of games that sustain active player communities rather than dispersing immediately after launch weekend.
The Development Achievement in Context
The July preview specifically examined what 570,000 demo players meant for a single-player dieselpunk artillery simulator — a genre combination with no obvious mass-market appeal. The conclusion was that the game had found a specific audience efficiently through viral discovery mechanisms that didn’t exist for earlier generations of indie developers.
The launch results confirm this. The two-person team that spent over a decade designing a giant spider-form turret has delivered a debut that sits in Steam’s top 5 at launch — not despite the extreme niche specificity of the concept, but because of it. The specificity is what made the game findable: “giant spider turret dieselpunk 1920s artillery simulation” is a search that returns one result, and the players who wanted that result found it.
The Post-Launch Roadmap
The development team announced a post-launch roadmap alongside the first-weekend results, confirming that launch is not the end of the game’s development. The specific content of the roadmap has not been detailed publicly — the announcement follows the “High Command” in-world marketing persona the team has maintained throughout development, which keeps the presentation in character.
The team also noted that review keys have been distributed to some press and content creators, requesting direct play rather than review coverage specifically — an approach consistent with a game whose appeal is fundamentally experiential and best communicated through watching someone actually operate the turret rather than reading a description of it.
For players who haven’t tried the game: the demo that accumulated 570,000 pre-launch players remains available on Steam.
