Lunarium launched on Steam on July 28, 2026, delivering an action RPG experience that combines hand-drawn visuals with souls-like combat mechanics [Source: store.steampowered.com]. The game features exactly 35 Steam achievements that track player progress across story progression, combat mastery, exploration milestones, and hidden secrets. Whether you're chasing the platinum or simply want to understand what lies ahead, this guide breaks down every single Lunarium achievement and provides practical tips for unlocking them.
Lunarium Achievement Overview
The 35 achievements in Lunarium span multiple categories, from straightforward story completions to challenging combat feats that demand precise timing and preparation. Each achievement carries a distinct unlock condition, and some are missable—meaning you cannot earn them after passing certain story checkpoints. The achievement list includes progress trophies that unlock automatically as you advance through the main storyline, alongside completionist trophies that require side content, collectibles, or specific playstyles.
Achievement Distribution by Category:
| Category | Count | Percentage |
|---|---|---|
| Story Progression | 12 | 34% |
| Combat & Skills | 10 | 29% |
| Exploration & Discovery | 8 | 23% |
| Secret & Hidden | 5 | 14% |
Understanding the split helps you prioritize which achievements to pursue during your first playthrough versus which ones require dedicated replay or meticulous exploration. For instance, the Five Star Chef achievement falls under the exploration category and requires finding specific ingredients scattered across multiple biomes—a task best approached with a prepared checklist rather than random wandering.
The Steam achievement population data shows mixed player reception at launch, with approximately 50% of the initial 20 user reviews giving positive feedback [Source: store.steampowered.com]. This indicates a challenging experience that rewards dedicated players who invest time in understanding Lunarium's mechanics deeply.
Story-Related Achievements
The story progression achievements form the backbone of Lunarium's achievement list, accounting for 12 of the 35 total trophies. These achievements unlock automatically as you advance through the main campaign, but understanding their sequence helps you avoid accidentally missing any during your playthrough.
Main Quest Milestones
The primary story achievements follow the critical path of Lunarium's narrative, tracking your progress from the opening moments through the final confrontation. Starting with First Steps, which unlocks upon completing the initial tutorial sequence, these trophies mark significant narrative beats rather than granular progression steps.
Key Story Achievement Chain:
| Achievement | Trigger Condition | Quest Phase |
|---|---|---|
| First Steps | Complete tutorial area | Prologue |
| The Wanderer | Reach the first open biome | Act 1 |
| Crossroads | Make the Moonstone choice | Act 1-2 Transition |
| Truth Seeker | Collect three memory fragments | Act 2 |
| The Reckoning | Confront the false prophet | Act 2 Finale |
| Lunacy Unchained | Defeat the lunacy embodiment | Act 3 |
The Crossroads achievement deserves special attention because it branches based on a choice involving the Moonstone—an ancient artifact that fundamentally alters your character's abilities and the world's reaction to you. Community reports indicate that both paths unlock the achievement, but the specific dialogue and NPC reactions differ significantly, which may affect related achievements like Silver Tongue if you pursue persuasion-based solutions in subsequent playthroughs.
Ending Achievements
Lunarium features multiple endings that correspond to specific achievement unlocks. The Lunacy Unchained achievement marks the default ending, but dedicated players can pursue alternative conclusions by making specific choices throughout the three acts.
Ending Achievement Breakdown:
| Achievement | Requirement | Playthrough Dependency |
|---|---|---|
| Lunacy Unchained | Complete default ending | Any |
| The Light Prevails | Choose redemption path at finale | Requires prior save |
| Shadows Embrace | Choose void path at finale | Requires prior save |
| Perfect Balance | Achieve both lunar and solar alignments | New Game Plus only |
The Perfect Balance achievement presents the most significant challenge, as it requires completing a New Game Plus run while maintaining specific stat thresholds and conversation choices that align with neither pure light nor pure shadow. This achievement is not missable in traditional terms—it simply cannot be attempted until you complete your first playthrough and unlock New Game Plus mode.
Combat and Skill-Based Achievements
Combat achievements comprise the second-largest category, with 10 trophies dedicated to proving your mastery over Lunarium's souls-like battle system. These range from simple milestone markers like "Defeat 100 enemies" to demanding technical feats that require precise execution of the game's combo mechanics.
Enemy Defeat Milestones
The kill-based achievements track your cumulative progress across all enemy types, rewarding sustained engagement with the combat system rather than requiring you to focus specifically on farming. Most players will naturally unlock these achievements through a complete playthrough.
Combat Progression Trophy Breakdown:
| Achievement | Requirement | Average Playtime to Unlock |
|---|---|---|
| Apprentice Warrior | Defeat 50 enemies | 3-4 hours |
| Seasoned Fighter | Defeat 200 enemies | 10-12 hours |
| Veteran Slayer | Defeat 500 enemies | 25-30 hours |
| Deathless | Complete any chapter without dying | Varies by skill |
| Flawless Victor | Defeat a mini-boss without taking damage | High skill requirement |
The Flawless Victor achievement specifically requires defeating a mini-boss—such as the Hollow Stalker or the Corrupted Knight—without receiving any damage during the encounter. This means no successful enemy attacks, environmental hazards, or poison damage. The best candidates for this achievement are early-game mini-bosses in the Wandering Woods biome, where you can access them before they gain access to their later, harder attack patterns.
Technical Skill Achievements
Beyond raw kill counts, Lunarium tests your technical execution through achievements tied to specific combat maneuvers. The game features a parry system that rewards precise timing, a combo system that chains attacks fluidly, and a stance system that changes your attack patterns based on equipped weapons.
Technical Achievement Requirements:
| Achievement | Mechanic | Difficulty |
|---|---|---|
| Perfect Parry | Execute 5 consecutive parries in one fight | Intermediate |
| Combo Master | Land a 20-hit combo | Intermediate |
| Dual Wielder | Defeat an enemy using only dual-wielded weapons | Advanced |
| No Stance Held | Defeat the same enemy using all three stances | Advanced |
| Lunar Arts | Execute the secret lunar combo sequence | Expert |
The Lunar Arts achievement requires discovering and executing a hidden combo sequence that is not taught through normal gameplay. Community data suggests this sequence involves specific timing with the Crescent Blade while in Moon Stance—holding the heavy attack button for exactly 0.3 seconds before releasing creates a distinctive visual effect that confirms the combo executed correctly. Multiple sources confirm that the combo window is punishingly precise, requiring practice in a safe area before attempting it against live enemies.
Exploration and Collectible Achievements
Lunarium's hand-drawn world contains numerous secrets tucked away in corners that casual playthroughs will miss. The eight exploration achievements reward thorough investigation, hidden area discovery, and collectible completion across all three acts.
Discoverable Location Achievements
Each biome in Lunarium contains hidden areas that are not marked on the map, requiring players to investigate unusual environmental details or followNPC hints to locate them. The Wanderer's Eye achievement tracks your total discovered locations, with milestones at 10, 25, and the full set of hidden areas.
Hidden Area Discovery Tiers:
| Achievement | Locations Required | Total Hidden Areas |
|---|---|---|
| Curious Explorer | Discover 10 hidden areas | 50+ total |
| Thorough Wanderer | Discover 25 hidden areas | 50+ total |
| Cartographer | Discover all hidden areas | 50+ total |
Hidden areas include collapsed caves behind destructible walls, rooftops accessible through specific climbing paths, and NPC homes that only appear after certain story events trigger. Some hidden areas contain memory fragments—collectibles that expand the game's lore and contribute to the Truth Seeker story achievement.
Collectible Category Achievements
Lunarium distributes multiple collectible types throughout its world, each with corresponding achievement milestones. Understanding the four collectible categories helps you develop an efficient gathering strategy.
Collectible Achievement Matrix:
| Achievement | Collectible Type | Required Count | Total Available | |---|---|---| | Relic Hunter | Ancient Relics | 15 | 20 | | Ingredient Gatherer | Alchemy Ingredients | 30 | 40 | | Lore Keeper | Memory Fragments | 10 | 12 | | Collector | All collectible types | Various | 72 total |
The Ingredient Gatherer achievement is particularly demanding because many alchemy ingredients are time-sensitive or event-dependent. Some herbs only bloom during specific in-game weather conditions, while certain monster drops only appear during the night cycle. Planning your ingredient runs around these cycles significantly accelerates progress toward the 30-item threshold.
Secret and Hidden Achievements
Five achievements fall into the secret category, meaning their descriptions are hidden until you unlock them. Some of these are straightforward alternate outcomes, while others require discovering obscure game mechanics or exploiting specific environmental interactions.
Secret Ending Prerequisites
Several secret achievements serve as prerequisites for Lunarium's hidden ending paths. These are not marked in any UI element and require players to piece together clues from environmental storytelling and NPC dialogue.
Secret Achievement Prerequisites:
| Achievement | Unlock Method | Visibility |
|---|---|---|
| Whispered Secret | Speak the password to the hermit | Hidden until unlocked |
| Moonlit Bargain | Trade the Moonstone at the shrine | Hidden until unlocked |
| Void Walker | Enter the forbidden zone without dying | Hidden until unlocked |
| Truth Above All | Collect all memory fragments before Act 3 | Hidden until unlocked |
| Beyond Lunacy | Trigger the secret ending | Hidden until unlocked |
The Truth Above All achievement exemplifies why the secret category is challenging—collecting all 12 memory fragments requires methodical exploration throughout all three acts, with the final fragment only becoming accessible after defeating the Act 2 boss. Players who miss even one fragment before this point cannot unlock the achievement without starting a new playthrough, making it effectively missable despite being story-progression adjacent.
Easter Egg Achievements
Beyond the mechanically significant secrets, Lunarium includes several achievements tied to optional interactions that break the fourth wall or reference developer inside jokes.
Easter Egg Achievement Reference:
| Achievement | Trigger | Notes |
|---|---|---|
| Cat Person | Pet the cat in every biome | Cat locations are semi-hidden |
| Speedreader | Skip all dialogue for one entire act | Does not affect story achievements |
| Completionist's Bane | Die to the same trap 10 times | Self-deprecating humor |
The Cat Person achievement tracks your interactions with Lunarium's feline population, which consists of five cats distributed across the major biomes. Each cat responds to a different interaction—some prefer being fed specific ingredients, others want to be pet at particular times of day. Community wikis have compiled cat location guides that significantly ease this achievement's requirements.

Frequently Asked Questions
How many Lunarium achievements are missable?
Approximately 8 of the 35 achievements are missable, primarily the secret category achievements tied to specific story choices and the Truth Above All achievement requiring all memory fragments collected before Act 3. The vast majority of achievements—including all combat milestones and exploration trophies—can be obtained across multiple playthroughs or in New Game Plus mode.
Can you unlock all Lunarium achievements in one playthrough?
No, achieving a 100% completion requires multiple playthroughs due to branching story choices, different ending paths, and the Perfect Balance achievement that mandates New Game Plus access.

What is the hardest Lunarium achievement to unlock?
Community consensus points to Perfect Balance as the most technically demanding achievement, requiring specific stat distributions, dialogue choices, and a New Game Plus completion without dying.

Are there any Lunarium achievements that require online features?
No, all 35 Lunarium achievements are obtainable entirely offline in single-player mode. The game does feature asynchronous multiplayer elements like ghost recordings and message stones, but none of these are required for any achievement unlock.
