How much does Lunarium for PC cost right now?

Lunarium for PC starts at €8.39 at Difmark, 53% under the €17.99 of the official store — but that is a shared account, not a key of your own. If you want a key tied to your own account, the cheapest is €17.99 at Steam.

That €8.39 already includes the Gocdkeys coupon, so apply it at checkout or the store will show you a higher price.

Supply is thin — 2 offers from 2 stores — and thin supply keeps prices steady rather than falling.

Which Lunarium format should you buy?

With the shared account at Difmark you log into an account that already owns the game: it is the cheapest route, but it never becomes yours and the seller keeps the credentials. If they ever lose or change them, you lose access.

The key at Steam costs €9.60 more, but you redeem it on your own account and the game stays there for good. That is the difference between renting and buying.

Can you activate Lunarium in US?

All 2 offers are Global, so the code redeems on any account no matter where it was created.

So, which Lunarium deal should you buy?

There is no third-party key on offer today, so the choice is between the shared account at €8.39 at Difmark — cheap, but the game never becomes yours — and paying the official €17.99 for a key on your own account. Either is defensible; just know which one you are picking.

Lunarium is an atmospheric isometric action RPG set in a crumbling world on the brink of collapse. You play as Ave, a light-armored knight, and journey alongside Lune, a mysterious magic user, as the two embark on a perilous quest to restore their dying homeland and uncover the cosmic secrets that bind them. The narrative unfolds across multiple worlds, revealing the intertwined fates of these two protagonists as they piece together ancient mysteries and confront the truth hidden within themselves.

Combat centers on precise, reaction-based mechanics that reward skillful play. As Ave, you execute perfectly-timed parries and dodges to neutralize incoming attacks, while Lune supports you with magic that weakens enemies and creates openings. The dual-protagonist system emphasizes synergy: building Resonance Points during battles strengthens the bond between Ave and Lune, allowing you to coordinate devastating attacks and push back against tougher foes. Each encounter demands adaptation and tactical awareness.

Progression is deeply customizable through multiple systems. You can modify Ave's combat style using Cloaks (which offer unique appearances and ability effects), Embroideries (equippable charms that provide passive bonuses), and a flexible Skill Tree. This layered approach ensures that no two playthroughs feel identical, allowing you to refine your strategy as you explore. Between battles, the Temple serves as a safe haven where you can craft and upgrade equipment using materials discovered during exploration.

The world itself is a character—each area features distinct atmospheres, terrain, and combat rhythms, from unguarded temples to ruins of fallen kingdoms shrouded in dark mist. The hand-drawn isometric art style creates an intimate yet expansive sense of place. The game offers two distinct endings, encouraging replayability and meaningful choice.

Lunarium appeals to action RPG fans who value skill-based combat, narrative depth, and build variety. If you enjoy games that balance challenging encounters with character-driven storytelling and reward mastery of mechanics, this indie title delivers a focused, memorable experience.
