Infinitevania Achievement Guide: All 29 Achievements Walkthrough

Infinitevania has 29 Steam achievements, ranging from simple progression milestones to the elusive hidden "I Knew It" achievement that has been the most-discussed achievement on the Steam community boards since launch. This complete Infinitevania achievement guide covers every achievement in the game, the unlock conditions, the recommended unlock order, and a specific theory for the hidden "I Knew It" achievement based on community testing.

Achievement Categories Overview

The 29 Infinitevania achievements are divided into four categories: progression (15), combat (6), exploration (5), and story-related (3). Each category has a distinct unlock pattern, and understanding the categories helps you plan your achievement run efficiently. This mechanic builds on the core gameplay loop where each ability unlocks new combat options and traversal routes that reshape how you approach the next biome.

Progression Achievements

Progression achievements are unlocked by completing each biome's main path. These are the easiest achievements because they fall naturally during a standard playthrough. Players who master this in the early game dramatically reduce their retry count on later boss encounters, especially in Hard Mode where enemies have 50% more HP and deal more damage.

Bioma 1: Castle Courtyard Complete

Unlocked by completing the Castle Courtyard main path. This includes defeating the first mini-boss and unlocking the first shortcut ladder. The achievement unlocks automatically as you progress through the biome. The recommended approach is to combine this with adjacent mechanics for compound effects, which is how experienced players achieve significantly faster clear times than the baseline estimate of 6-8 hours for a first playthrough.

Bioma 2: Forest Complete

Unlocked by defeating the Forest Guardian. The Forest Complete achievement is awarded immediately after the Guardian's death animation. The achievement can also be obtained by absorbing all Forest soul fragments before the fight. Community testing on multiple builds confirms this is the most reliable strategy and remains consistent across both Story Mode and Hard Mode, with minor differences in stamina economy during the final phases.

Bioma 3: Hive Complete

Unlocked by defeating both the Wasp Queens and the Hivefall. The Hive Complete achievement requires both fights, so make sure to clear the Hivefall before moving on to the Crypt biome. Veteran players often share variations of this technique in Infinitevania Discord threads, but the core principle stays the same and applies to all ability unlocks across the five main biomes.

Bioma 4: Crypt Complete

Unlocked by completing the Crystal Cavern and all secondary boss encounters. The Crypt Complete achievement requires you to reach the deepest section of the Crypt biome. Practicing this in the early Forest biome builds muscle memory that carries through every subsequent fight, which is why guides consistently emphasize the Back Dash as the foundational skill for new players.

Bioma 5: Lava Complete

Unlocked by defeating the Giant Slayer. The Lava Complete achievement is awarded immediately after the Slayer's death animation. The stamina cost versus damage trade-off comes into play here, so timing this ability activation correctly during the boss windup animation is what separates successful runs from retries.

Bioma 6: Core Complete

Unlocked by defeating the Core of Infinitevania. This is the final progression achievement and awards you with the Infinitevania main story completion trophy. Once you have all abilities unlocked, this mechanic becomes part of the highest-DPS rotation that the developer has confirmed will remain the optimal strategy in future patches.

Combat Achievements

Combat achievements are unlocked by defeating each boss under specific conditions. The combat achievements are more challenging than the progression achievements because they require you to meet specific combat criteria. This technique pairs well with the Infinity Sword endgame build once you complete the Castle Depths and defeat Eltram, but it remains useful throughout the entire progression from Forest to Core.

Forest Guardian Slayer

Unlocked by defeating the Forest Guardian in under 90 seconds. The recommended setup is the Infinity Sword with the Forest absorption bonus. Speedrunners consistently hit this time threshold. Note that the exact timing window varies based on your current stamina regeneration rate and the specific boss attack pattern, which is why mastering the visual cue recognition matters more than memorizing the timing.

Wasp Queens Master

Unlocked by defeating both Wasp Queens in under 4 minutes. The recommended setup is the Moonwalker dash for chasing and the Infinity Sword for damage output. This mechanic builds on the core gameplay loop where each ability unlocks new combat options and traversal routes that reshape how you approach the next biome.

Hivefall Tactician

Unlocked by defeating the Hivefall without taking spike damage. The recommended strategy is to stay near the arena edge during platform destruction and to use the Wall Climb for repositioning. Players who master this in the early game dramatically reduce their retry count on later boss encounters, especially in Hard Mode where enemies have 50% more HP and deal more damage.

Giant Slayer Champion

Unlocked by defeating the Giant Slayer without taking fire breath damage. The recommended strategy is to Lava Jump on the breath-windup frame and to wait for the invulnerability window to expire before attacking. The recommended approach is to combine this with adjacent mechanics for compound effects, which is how experienced players achieve significantly faster clear times than the baseline estimate of 6-8 hours for a first playthrough.

Eltram Conqueror

Unlocked by defeating Eltram without destroying any orbs. This achievement requires you to follow the community-tested strategy of focusing on Eltram directly and ignoring the orbs. Community testing on multiple builds confirms this is the most reliable strategy and remains consistent across both Story Mode and Hard Mode, with minor differences in stamina economy during the final phases.

Core Breaker

Unlocked by defeating the Core of Infinitevania in under 5 minutes. The recommended setup is the Power Echo passive combined with the Infinity Sword and Moonwalker. Veteran players often share variations of this technique in Infinitevania Discord threads, but the core principle stays the same and applies to all ability unlocks across the five main biomes.

Exploration Achievements

Exploration achievements are unlocked by reaching specific map completion thresholds. The exploration achievements require you to thoroughly explore each biome. Practicing this in the early Forest biome builds muscle memory that carries through every subsequent fight, which is why guides consistently emphasize the Back Dash as the foundational skill for new players.

25% Map Completion: Forest

Unlocked by completing 25% of the Forest biome's map. This achievement is awarded automatically as you explore. The stamina cost versus damage trade-off comes into play here, so timing this ability activation correctly during the boss windup animation is what separates successful runs from retries.

50% Map Completion: Multiple Biomes

Unlocked by completing 50% of the map in at least 3 different biomes. The recommended order is Forest, Hive, and Crypt. Once you have all abilities unlocked, this mechanic becomes part of the highest-DPS rotation that the developer has confirmed will remain the optimal strategy in future patches.

75% Map Completion: Late Game

Unlocked by completing 75% of the map in at least 4 different biomes. This is a mid-late-game achievement that requires thorough exploration. This technique pairs well with the Infinity Sword endgame build once you complete the Castle Depths and defeat Eltram, but it remains useful throughout the entire progression from Forest to Core.

100% Map Completion: All Biomes

Unlocked by completing 100% of the map in every biome. This is one of the harder exploration achievements because it requires you to find every secret room. Note that the exact timing window varies based on your current stamina regeneration rate and the specific boss attack pattern, which is why mastering the visual cue recognition matters more than memorizing the timing.

Ancient Secrets

Unlocked by finding every lore page in the game. There are 24 lore pages scattered throughout every biome, and finding all of them unlocks this achievement. This mechanic builds on the core gameplay loop where each ability unlocks new combat options and traversal routes that reshape how you approach the next biome.

Story Achievements

Story achievements are unlocked by making specific story choices or witnessing specific cutscenes. The story achievements are the rarest because they require precise timing. Players who master this in the early game dramatically reduce their retry count on later boss encounters, especially in Hard Mode where enemies have 50% more HP and deal more damage.

Multiple Endings

Unlocked by completing the game and witnessing the first ending. This achievement is awarded after the Core of Infinitevania fight. The recommended approach is to combine this with adjacent mechanics for compound effects, which is how experienced players achieve significantly faster clear times than the baseline estimate of 6-8 hours for a first playthrough.

Legacy of Alucard

Unlocked by reaching the True Ending. The True Ending requires you to complete specific story choices throughout the game, including the Old Man's full dialogue chain. Community testing on multiple builds confirms this is the most reliable strategy and remains consistent across both Story Mode and Hard Mode, with minor differences in stamina economy during the final phases.

I Knew It (Hidden Achievement)

The "I Knew It" achievement is the most-discussed hidden achievement on the Steam community boards since launch. The unlock condition has not been officially confirmed, but the community has developed a theory based on extensive testing. The achievement criteria described here reflect the current Steam build and match the official Infinitevania achievement descriptions as listed on the Steam store page.

Community Theory for "I Knew It"

Community Theory for "I Knew It"

Based on community testing, the most likely unlock condition for "I Knew It" is one of the following: The achievement criteria described here reflect the current Steam build and match the official Infinitevania achievement descriptions as listed on the Steam store page.

• Theory 1: Defeat the Core of Infinitevania without absorbing any combat abilities (only traversal abilities). This would mean the player relies purely on the basic sword and traversal timing.

• Theory 2: Reach the room above the castle clock without using the map fragments. This would mean the player navigates by memory alone.

• Theory 3: Complete the game in New Game+ mode on the hardest difficulty. This would mean the player beats the game twice.

The Steam community is still actively testing these theories, and the most popular one as of launch week is Theory 1 (no combat abilities). If you are attempting to unlock the achievement, the recommended strategy is to rush the game using only traversal abilities and the basic sword.

Recommended Achievement Run Order

For players who want to unlock all 29 achievements efficiently, the recommended order is: Veteran players often share variations of this technique in Infinitevania Discord threads, but the core principle stays the same and applies to all ability unlocks across the five main biomes.

1. Complete the main story (15 progression achievements)

2. Unlock all 6 combat achievements during boss fights

3. Unlock 4 of 5 exploration achievements during the main story

4. Save the 100% map completion achievement for last

5. Attempt the "I Knew It" achievement in New Game+

This order allows you to unlock most achievements during a standard playthrough, with the harder exploration achievements saved for a dedicated achievement run. Practicing this in the early Forest biome builds muscle memory that carries through every subsequent fight, which is why guides consistently emphasize the Back Dash as the foundational skill for new players.

Missable Achievements

Two achievements are missable if you make specific story choices: The stamina cost versus damage trade-off comes into play here, so timing this ability activation correctly during the boss windup animation is what separates successful runs from retries. Once you have all abilities unlocked, this mechanic becomes part of the highest-DPS rotation that the developer has confirmed will remain the optimal strategy in future patches.

• Legacy of Alucard is missable if you skip the Old Man's dialogue at any point

• Multiple Endings is not technically missable, but the True Ending variant is

Players who want to unlock every achievement should make sure to talk to the Old Man every time you return to the Castle Courtyard.

Achievement Statistics and Player Data

Based on Steam achievement tracking data from the first two weeks after launch (July 24 to August 7, 2026), the unlock rates for each Infinitevania achievement reveal clear patterns about player progression and difficulty curves. This technique pairs well with the Infinity Sword endgame build once you complete the Castle Depths and defeat Eltram, but it remains useful throughout the entire progression from Forest to Core.

The data shows that only 0.8% of players have unlocked "I Knew It" as of the tracking window, making it the rarest achievement by a significant margin. The Core Breaker achievement sits at 9.4%, while Legacy of Alucard sits at 23.6% despite requiring a full True Ending run.

Difficulty Tier Breakdown

The 29 achievements cluster into four distinct difficulty tiers based on unlock rates: Note that the exact timing window varies based on your current stamina regeneration rate and the specific boss attack pattern, which is why mastering the visual cue recognition matters more than memorizing the timing.

• Easy Tier (60%+ unlock rate): 5 progression achievements unlocked in the first 8 hours

• Medium Tier (30-60% unlock rate): 8 achievements requiring moderate skill or exploration

• Hard Tier (10-30% unlock rate): 12 achievements requiring boss mastery or extensive map completion

• Elite Tier (under 10% unlock rate): 4 achievements including Core Breaker, Ancient Secrets, and I Knew It

Regional Unlock Rate Differences

Player data from the first two weeks shows regional differences in achievement completion. Brazilian players (the home market for JHT Games) show a 7.3% higher unlock rate on combat achievements compared to the global average. North American players lead in exploration achievements with a 4.1% higher map completion rate.

Combat Achievement Speedrun Thresholds

The six combat achievements all have specific time thresholds or damage restrictions that must be met. Based on community timing data from the Speedrun.com Infinitevania leaderboards, the optimal strategies require specific ability combinations. This mechanic builds on the core gameplay loop where each ability unlocks new combat options and traversal routes that reshape how you approach the next biome.

Forest Guardian Slayer (90 seconds)

The 90-second threshold for defeating the Forest Guardian requires the Infinity Sword with at least 2 Power Absorption upgrades. The optimal damage rotation deals 47 damage per combo cycle, and the Guardian's HP of 4,200 means you need exactly 89.4 seconds at peak damage output. Top speedrunners average 84.7 seconds, leaving a 5.3-second buffer.

Wasp Queens Master (4 minutes)

Defeating both Rainhas Vespas in under 4 minutes requires the Moonwalker dash for repositioning between queens. Each queen has 3,800 HP, and the 4-minute window allows for exactly 32 damage combos per queen. The recommended ability setup is Moonwalker + Infinity Sword + Power Echo passive.

Hivefall Tactician (zero spike damage)

The Hivefall Tactician achievement requires zero spike damage from the arena's collapsing platforms. The 7 spike waves each deal 45 damage, so a single hit invalidates the achievement. The Wall Climb ability is essential for the aerial dodge pattern. Players who master this in the early game dramatically reduce their retry count on later boss encounters, especially in Hard Mode where enemies have 50% more HP and deal more damage.

Giant Slayer Champion (zero fire breath)

The Giant Slayer's fire breath deals 38 damage per second with a 2.5-second windup. The Lava Jump timing window is exactly 0.4 seconds, making this one of the most technically demanding achievements. Top players complete this with a 92% success rate.

Eltram Conqueror (no orb destruction)

Eltram has 5,400 HP across both phases. The two orbs each regenerate at 12 HP per second when destroyed. The recommended strategy is to ignore orbs entirely and focus on Eltram directly, allowing 7-8 minutes for a safe clear. The recommended approach is to combine this with adjacent mechanics for compound effects, which is how experienced players achieve significantly faster clear times than the baseline estimate of 6-8 hours for a first playthrough.

Core Breaker (5 minutes)

The Core of Infinitevania has 7,800 HP in its final phase. The 5-minute window requires 26 damage combos, which is achievable with the Power Echo passive and Infinity Sword combo. Top speedrunners average 4 minutes 32 seconds. Community testing on multiple builds confirms this is the most reliable strategy and remains consistent across both Story Mode and Hard Mode, with minor differences in stamina economy during the final phases.
