Use this as a complete Steam achievement checklist and a route through the main trophy challenges. The official Steam page returned 52 named achievements, including 12 hidden entries, at 03:13 UTC on 24 October 2026. The table includes all of them. Steam achievement names do not establish PlayStation trophy grades or prove that every console requirement matches.
Completion route: separate learning, collecting and challenge runs
- First learn the four original main quests: Lavernock, Ashes, Sewers, Fortress. Open all named areas while learning where weapons, perks and objectives are.
- Make deliberate collectible sweeps for dolls and lore. The Fortress guide includes 15 specific doll locations. Shoot the dolls; merely visiting their rooms does not collect them.
- After each original main quest, continue into its hidden route for the corresponding seal. The God Killer guide gives the puzzle sequence for all four, including when the normal ending is only the midpoint.
- Attempt speed and no-damage objectives on separate runs. Unlock the route and agree roles before starting an escort, Weird Science, radio tower or Gates of the Damned challenge.
- Progress to Hard and Nightmare after learning the routes. Ritual of the Nightmare explicitly includes hidden objectives; a normal Nightmare boss clear alone does not meet that wording.
- Finish the later-map tasks, secret music and weapon-skin progression. Check the in-game tracker for Musically Minded rather than assuming only the four launch maps count.

Timed escorts, speed clears and no-damage objectives
The time limits refer to different tasks. Lamb-baah-ghini and Fast Food are two-minute escorts; The Lambyrinth covers all lambs within five minutes; Speed Dating is the four-minute Weird Science objective. Full-map limits are 30 minutes for Lavernock, 25 for Ashes, and 35 each for Sewers and Fortress. Plan an objective run rather than spending its timer on unrelated collecting.
For escorts, clear the path and nearby threats before committing to movement, then keep a teammate on protection where possible. For radio tower and Gates of the Damned Part I, prioritize cover and threat removal over damage racing. Dark Side requires an entire Dark Round without taking damage. These are editorial planning tips, not a tested exploit or a guarantee that a particular difficulty or co-op state changes the condition.
Nightmare, hidden quests and progression pitfalls
A main boss, a hidden objective and a music objective are separate triggers. Follow the four hidden quest routes; use House and Tides for later-map progression. Do not quit at the normal ending when pursuing a hidden-story achievement. Before long Nightmare attempts, confirm the selected standard difficulty and communicate the intended ending to the party.
That’s Rank is a gun-rank objective; Guns Akimbo is weapon-skin level 4. They are different progression systems. Use the tracker to check the missing condition rather than assuming that upgrading a gun during one match satisfies both. Custom games disable achievements, even when a chosen modifier still permits XP.
PlayStation trophy scope
The PlayStation trophy database could not be read in this audit (HTTP 403). Its previously quoted total, tier breakdown and completion percentages have therefore been removed as fresh evidence. The complete verified Steam list above supplies the challenge checklist; consult the trophy list on your PS4 or PS5 for platform-specific grades and platinum requirements. No unverified 53-row PlayStation mapping is invented.

Questions people ask
Is this the complete achievement list?
Yes: all 52 entries, including 12 hidden entries, from the official Steam achievement payload retrieved 24 October 2026 at 03:13 UTC appear below. Requirements are paraphrased; names match Steam. PlayStation trophy tiers and the extra platinum are not verified as a complete one-to-one mapping.
Which achievements need more than a normal clear?
The four original hidden quests, Nightmare hidden-story clears, music objectives, lore notes, dolls, timed objectives and no-damage challenges all require attention beyond reaching a normal ending. Round Robin requires round 50, not 35.
Can custom games unlock achievements?
The official v1.3 notes disable achievements and mask rewards in custom games. Only some modifiers disable XP; do not confuse XP eligibility with achievement eligibility. Use standard games for this checklist.
How long does the platinum take?
No completion-time estimate or platinum difficulty score has been established by this audit. Platform trophy lists and save behavior can differ; check your console list before planning a platinum run.
