Atmospheric fantasy action-RPGs have quietly built a devoted Steam following through titles like Salt and Sanctuary, Hollow Knight, and Blasphemous. Lunarium joins this lineage with its light-armored knight archetype and the dying-world premise — narrative anchors that give the atmospheric combat a purpose beyond mere spectacle.

The dual-publisher setup with Imperfect Games as co-publisher signals meaningful industry support for what appears to be a Chinese-developed indie project. Publisher co-signing typically means the port, localization, and Western marketing are being handled at higher standards than pure self-publishing achieves.

Lunarium gameplay — Ave, Lune, and the dying world

How the game is officially described: “Lunarium is an atmospheric fantasy A-RPG. Play as Ave, a light-armored knight, who teams up with Lune, a mysterious Starfarer. Together, they journey to save a dying world, engaging in challenging battles.”

Translated into practical Lunarium play: expect responsive action combat suited to Ave’s light-armor archetype (dodge-focused rather than tank-focused), with Lune providing companion mechanics — likely support abilities, secondary attacks, or narrative-driven interactions. The dying-world setting provides narrative stakes without needing to explain everything upfront; players will discover the world’s decay through exploration and combat encounters.

Light-armored knight builds in action RPGs traditionally reward players who prioritize positioning over defensive stats. Games like Hollow Knight, Salt and Sanctuary, and the modern Metroidvania wave have proven this archetype works excellently when combat is tuned to reward mobility.

Lunarium and the Starfarer companion mechanic

Lune as a “mysterious Starfarer” companion suggests either NPC-managed AI support (common in Ori and the Will of the Wisps’ Ku sections) or dynamic party mechanics where Lune’s abilities interact with Ave’s core combat. Either interpretation adds tactical depth beyond solo action combat.

The “mysterious” descriptor is a specific narrative choice. Companions who have hidden backgrounds create story pull — players want to learn who Lune actually is, which drives forward momentum through the game’s dying-world exploration.

Lunarium and the developer profile

The developer name 月相仪Lunarium blends Chinese characters with the Latin script name. 月相仪 translates as “moon phase instrument” — a poetic name that fits the atmospheric-fantasy tonal register. Chinese indie studios have delivered some of the strongest action-adventure titles of the past several years (Black Myth: Wukong is the AAA end of this spectrum, but the indie tier is producing consistently strong work).

Imperfect Games as co-publisher provides Western market support and likely localization quality control. This partnership pattern — Chinese developer plus Western-facing publisher — has become common for cross-market indie releases.

Lunarium PC requirements and hardware compatibility

Atmospheric fantasy action RPGs with stylized art typically have moderate system requirements. Any Windows PC from the past 5 years with a mid-range dedicated GPU should handle Lunarium without issue. The atmospheric visual style suggests careful art direction rather than raw graphical intensity, which usually means efficient rendering rather than punishing GPU demands.

Steam Deck compatibility is worth checking on the listing — atmospheric action-RPGs have been mixed on Deck depending on combat intensity and text readability at handheld scale.

Similar atmospheric action-RPGs worth exploring

If Lunarium appeals to you, adjacent Steam titles include:

• Hollow Knight — the modern atmospheric Metroidvania benchmark
• Salt and Sanctuary — 2D Souls-like with atmospheric world-building
• Blasphemous — dark atmospheric action with strong narrative tone
• Ori and the Will of the Wisps — beautiful action-platformer with companion mechanics
• Ender Lilies — atmospheric Metroidvania with companion spirits

Lunarium sits closest to Ori’s companion-driven combat pairing with atmosphere-first storytelling closer to Hollow Knight. The specific dying-world premise gives Lunarium its own narrative identity.

Should you buy Lunarium at launch?

For atmospheric action-RPG fans, this is an easy try. The Ave-Lune companion dynamic, dying-world setting, and light-armor combat archetype suggest a game designed for players who prioritize atmosphere and narrative depth alongside mechanical challenge. Steam 2-hour refund window gives you room to test the specific combat feel.

For players seeking modern AAA production values: adjust expectations toward indie scale. Lunarium is atmospheric-first, budget-appropriate rather than AAA-scoped.

For players who loved Hollow Knight, Ori and the Will of the Wisps, or Ender Lilies: Lunarium is likely to resonate strongly. The design DNA is directly related, applied to a fresh setting.
