The 'Botanist' Achievement
Description: Fully upgrade all Growth Inhibitor types. To achieve this, you must find all 5 'Botanical Research Notes' and collect enough 'Rare Chemical Compounds' to perform the upgrades at a workbench. This requires thorough exploration, especially in the Old Clinic and the Research Facility.
The 'Pacifist' Achievement
Description: Complete the game without killing any non-boss enemies. This is a highly challenging achievement that requires extensive use of stealth, environmental avoidance, and precise dodging. You'll need to master the 'Perfect Dodge' and use distractions to bypass encounters. Boss fights are exempt from this requirement.
The 'Collector of Whispers' Achievement
Description: Find all 10 'Cursed Dolls' and complete 'The Cursed Dolls Collection' side quest. Refer to the 'Side Quests & Activities' section for detailed locations and steps.
The 'True Ending' Achievement
Description: Unlock the game's most elusive ending. This requires completing all major side quests, finding all 'Lost Photographer's Journal' entries, and making specific moral choices during key narrative moments. It also involves finding a hidden 'Ritual Scroll' in the 'Forbidden Archives' (accessible only after completing the 'Hidden Path' side quest) and using it at the final boss encounter.
The 'Speedrunner' Achievement
Description: Complete the game in under 3 hours on any difficulty. This achievement demands intimate knowledge of the game's layout, enemy placements, and puzzle solutions. Focus on main objectives, skip all optional content, and optimize your movement and combat efficiency. New Game+ can make this easier due to upgraded gear.
