What does completing the achievement list require?
Silver Pines has 23 Steam achievements covering story milestones, three endings, collectibles, upgrades and three extra actions. Exophase lists those same 23 objectives plus a PS5 platinum. Use the checklist below to identify your remaining goals; it does not guarantee a missable-free run.
Spoilers: the list names bosses, locations and ending objectives. It does not explain the story behind the endings.
Which missability risks need attention?
Permanent missability is unresolved. Steam players disagree about whether all collectibles can be recovered, especially after leaving dream areas. A completed achievement list from another player does not establish a recovery path for your save.
An October 6 third-party collection guide flags Chipped Ceramic Bear, Corroded Iron Ball and Snake Earring as possible misses. These are reported risk items, not three confirmed permanently missable trophies. The practical precaution is to inspect a newly opened area and the aftermath of a boss encounter before moving on, and compare any pickup with your remaining collection goals.
If you are approaching the end, follow the save preparation before the final choice. That advice preserves a point from which to approach the ending choices; it does not prove that an earlier missed collectible can be recovered. Treat an ending-choice save and an earlier exploration save as solving different problems.
Cat Collar needs a separate check. An October 2026 Steam thread describes a glowing collar that cannot be collected. A player suggests advancing NPC conversations and returning, but the reply does not identify the NPCs or their exact order. There is no reliable step-by-step fix in this edition. A blocked interaction is not by itself proof that a story choice permanently locked the item.
If an achievement stays locked, record its name, your platform, the item or action involved and where progression stopped. Those details help distinguish a missing objective from an interaction problem. Do not restart a long run solely because one report calls an item missable.
What do the collection achievements count?
The game files for build 25806663 specify targets of 11 collectible maps, 25 Mementos and 7 stamina upgrades. These are achievement target values. They do not establish a complete route to every item or certify that every marker in a map tool can be collected in one state of the game.
Use the interactive map to locate relevant points and plan where to inspect next. Keep a separate record of what you actually picked up: finding a marker on the website is not the same as adding its item to your save. For an apparent final missing collectible, match its displayed item name rather than adding together every object shown in an area.
For Walking Storage Box, the official goal is the full set of inventory upgrades. Hip Bags expand inventory; their game description says each adds two slots. This edition does not supply a verified total bag count, so the size of your current inventory is not used here as proof that the achievement should already have unlocked.
For Parts left behind and Memento Mori, focus on equipment capacity rather than collecting more Mementos. The game describes a Memento Vessel as a slot expansion. An October 9 third-party guide reports the sequence as collecting four vessel shards, combining them into a vessel and consuming it. Having the shards is therefore an earlier step in that reported process, not its endpoint.
The second-slot and all-slots objectives have different stopping points. This guide supplies the supported vessel method but leaves the total shard count and number of required expansions open. It does not convert internal configuration numbers into a shopping list.
How to make the calls and pet the cat
A Call for Help: use a payphone to dial 911. Steam names the call as the objective; one third-party guide reports using a coin at the payphone. Keep a coin available when approaching a phone if you still need this action.
Call me...: the target is Room 3 at the Crimson Bear, rather than an arbitrary phone call. A third-party guide directs players to the motel booklet in the Grizzly Suite and then to a payphone. Use the booklet to identify the call; this guide does not substitute a gun-locker code for the room's phone number.
Moment of calm, Brief respite: look for the cat at the ferry station, as an October 9 third-party guide describes. An October 6 third-party guide recommends doing this before calling the ferry: interact with the cat, let it move, then interact again. That is a reported action sequence, not evidence that the achievement becomes permanently unavailable afterward.
These three actions are useful to check separately from your story progress. Reaching a destination or completing a boss objective does not itself tell you whether you made either call or interacted with the cat. Compare the corresponding platform entries before treating that area's achievement work as finished.
How the three ending achievements fit together
The three ending goals need different actions. Use the linked routes for their preparations and full steps; the short platform descriptions alone leave out the collection work.
- Leave: the reported route fulfills the contract by killing Eddie Velvet. Follow the Leave ending steps.
- Live: the reported route spares Eddie and uses the collected Mementos at the furnace by the Burnt Man. Follow the Live ending preparations and route.
- Rest: the reported route involves the Gold Rings and a return to the Rabbit Hole. Follow the Rest ending route.
At the final conversation, the button labeled Leave is the option that spares Eddie. It is not a shortcut to the achievement called Ending: Leave. Keep the button text and the ending name separate when following the instructions.
The developer said on October 1, 2026 that every ending could be reached on one save. That pre-launch statement concerns endings; it does not establish that every collectible or trophy can be recovered from any late-game save.
Does Nightmare or a 100% result matter?
The complete Steam objective list contains no dedicated difficulty achievement. None of its listed goals asks for a Nightmare clear. Whether every modifier leaves achievement eligibility unchanged is still unconfirmed, so this edition does not prescribe a modifier-assisted completion route or extend the Steam finding into a platform-wide guarantee.
The game's results percentage is a different measure from your platform achievement list. In an October 11, 2026 Steam reply, developer knas says the percentage includes non-consumable items, Mementos and scene exploration, and that reaching 100% adds no extra reward.
Check the missing achievement's own objective rather than using the results percentage as a progress counter for it. A percentage below 100 does not identify which trophy is missing, and a completed platform list does not tell you which scene or item contributes to that separate score.
Version notes and limits
This edition stops short of a complete pickup-and-recovery route. It will expand when reliable evidence establishes dream-area returns, the flagged items' recovery paths, Cat Collar prerequisites, or the remaining upgrade totals. A current developer statement or reproducible evidence about modifiers would also change the difficulty guidance.
No author gameplay test was used for this guide.
Achievement FAQ
How long does the platinum take?
There is no supported platinum-time estimate in this edition. The game-length breakdown separates available playtime estimates; do not treat a main-story estimate as a promise for finding every collectible and completing the trophy list.
Should I start a new run for one missing achievement?
First identify the missing objective and check the relevant section above. A collection gap, an unused vessel and a missed optional action call for different checks. The available evidence does not justify a blanket instruction to restart, or a promise that continuing your current save will solve every case.
Can I use this as a complete location checklist?
No. This is a complete Steam objective list with selected action guidance. It does not list every collectible location or verify a route through all of them. Use the collection section to understand the targets and the linked guides for the routes they cover.
