Overview
Amberspire places you on an abandoned moon orbiting a gas giant named Amber. The task is city building, but the systems underneath it are governed by dice: which resources arrive, which buildings activate, what weather rolls through, and which events disrupt your plans. Citizens develop based on what's around them. Silica grass, fog banks, viscous floodplains — each affects who settles nearby and how they behave. Factions compete for control, and their disputes shape what your city can actually do on any given day.
Developed by Lunar Division and published by Bithell Games, the game is available now with a 10% introductory discount running through May 13. It includes 17 Steam achievements, Steam Cloud, and Family Sharing. No multiplayer at launch.
What Happened
Amberspire launched today following development that began after The Banished Vault — Lunar Division's 2023 space survival title. That previous game put players inside a Gothic monastery spaceship navigating procedurally generated solar systems, managing crew survival through permadeath-adjacent consequences and dice-based challenge systems. It earned Mostly Positive reviews on Steam (79% of 187 ratings), with critics at Eurogamer and Paste citing its singular design as distinguishing it from the broader strategy field.
Amberspire moves the same studio into a different genre. City building replaces crew survival, an alien moon replaces deep space — but the underlying bet is the same: dice aren't seasoning on top of fixed systems. They run the whole thing. Resources, buildings, weather, and events all resolve through dice — four domains at once, rather than the single-event-layer approach most city builders take.
The game ships with hand-drawn isometric art and an original score.
Why It Matters
The default architecture of a city builder assigns resources fixed production rates and treats randomness as an event modifier — a disaster reduces your copper output by 15%, a festival boosts morale for a day. Amberspire inverts this: the dice come first, and the loop around them adapts accordingly.
Whether this holds up over a full session is something hands-on time will answer. The more interesting structural question is what it means that Lunar Division has now built dice-as-foundation into two consecutive games. That's not a feature — it's a design position. Studios that commit to a design position across multiple games either build something recognizable around it or keep running into the same wall. Which side Amberspire lands on won't be clear until reviews arrive.
There's also the hardware question. Complex strategy games routinely assume a dedicated GPU and 16GB RAM as a baseline. Amberspire's minimum is a 1.4 GHz Core i5, 4GB RAM, and integrated graphics — hardware most people already have. A genre that frequently prices out its own audience doesn't have to, and this one apparently isn't.
For comparisons within the dice-driven strategy space: our Die in the Dungeon review covers how that game builds its progression system entirely around dice-as-equipment, which is a useful contrast when evaluating scope. Gambonanza takes a different approach — dice as chaos layer over a chess-based card structure. Both show the range of what "dice-driven" can mean before Amberspire reviews establish where this one lands.

Frequently Asked Questions
What is Amberspire? Amberspire is a single-player science fantasy dice city builder developed by Lunar Division and published by Bithell Games. You build a city on an abandoned moon beneath a gas giant, managing resources, citizens, factions, and a reactive alien ecology — all governed by dice.
Who made Amberspire? Lunar Division developed the game; Bithell Games published it. Lunar Division's previous title was The Banished Vault (2023), a space survival strategy game that earned Mostly Positive reviews on Steam.
Is Amberspire on sale at launch? Yes. A 10% introductory discount runs through May 13, 2026 on Steam. After that it returns to standard pricing.
What platforms is Amberspire on? Windows and macOS at launch. Minimum specs are Windows 10 or macOS Monterey 12.3.1, a 1.4 GHz Core i5 or Apple M1, 4GB RAM, integrated graphics, and 4GB storage.
How does Amberspire's dice system work? Dice govern four distinct systems simultaneously — resources, buildings, weather, and events. That's a broader role than most dice-driven games assign to randomness, which usually confine it to one system while the rest runs on fixed rates.
Is Amberspire related to The Banished Vault? Not narratively. Both games share hand-drawn art and dice-based systems built around the principle that randomness should be foundational rather than decorative. Amberspire is city-building; The Banished Vault was crew survival on a Gothic monastery spaceship.
