Project Solaris Multiple Endings (Spoiler-Light)
Understand how branches form from choices and milestones — keep specific plot twists to yourself until you are ready.
Project Solaris is a scenario-driven JRPG. Beyond the mechanical 100-day loop, your run is judged by choices, milestones, and side stories that open multiple endings. This page stays spoiler-light: it explains how endings form and what systems to watch, without naming twist outcomes, secret identities in detail, or step-by-step route charts that ruin first plays. For cast names without full plot dumps, use the Players Hub. For the calendar that carries those choices, use 100-Day Strategy.
What “multiple endings” means here
Endings are not a single hidden boss toggle. They emerge from the same daily structure you already use: which action cards you honor, which character scenes you attend, which milestones you hit before Trial Ceremonies, and how far Trust and side routes progress with Hom and the wider cast. A mechanically perfect Day 100 clear and a story-complete clear can be different goals. Decide which you want on a given save.
Three inputs that shape branches
1) Choices
Dialogue and event decisions matter. When the game offers a clear fork, assume it is stored. If you are ending-hunting, slow down on Social days and story flags — mashing through text is how players miss the only soft requirement for a branch. Mechanical guides like Combat QTE will not warn you about a dialogue flag; your attention will.
2) Milestones
Calendar milestones (elite windows, ~20-day ceremonies, Day 100) are story gates as well as combat gates. Surviving them keeps routes alive; failing them can lock or shade outcomes depending on the scenario design. Treat ceremony prep from 100-Day Strategy as both a DPS plan and a story-continuity plan.
3) Side stories
Side stories often hitch to Social / Development cards and cast focus: classmate Tetia, mother Croisé / Croise, shopkeeper August, Melchior of The Three, and other figures including a secret antagonist thread the scenario seeds carefully. This page will not spell the antagonist’s identity or end states. It will say: if a side story offers time with a character, that time is frequently ending-relevant.
Trust is an ending resource too
Trust and Bond frames Reliability as a QTE enabler. It is also a relationship flag. Ignoring Social forever can close emotional routes even if your yellow timing is perfect. Conversely, all-Social runs that skip combat prep may fail milestones required to see an ending at all. Balance remains the rule.
Spoiler-safe hunting method
- Clear once mechanically. Learn cards, QTEs, shopkeeping, and ceremonies with Getting Started, Shopkeeping, and combat guides.
- Note scenes you skipped. After a first ending, jot which characters you rarely visited.
- Second save: pick a focus character or theme. Attend their Social offers consistently without abandoning ceremony prep.
- Compare milestone coverage. Did you hit the same Day 10 / Trial checkpoints?
- Only then seek detailed route spoilers off-wiki if you want exact flags. This wiki page stops before that line on purpose.
What we deliberately do not list
- Named ending titles and their cinematic outcomes
- Exact antagonist reveals
- Checklist flags that remove surprise from side stories
- “Do X on Day Y” spoilers that duplicate a full walkthrough chart
If you came here for those, pause. Finish a blind-leaning run. The pixel-art scenario from Greenhorn / IndieArk is built for discovery inside the 100-day frame.
Systems still required for ending clears
Story focus does not erase:
- QTE competence — Combat QTE, Controls
- Money and crafts — Shopkeeping
- Calendar honesty — 100-Day Strategy
- Bond maintenance — Trust and Bond
Day 100’s final Trial still demands execution. Ending flags rarely save a run that cannot yellow under pressure.
Cast compass (non-spoiler)
- Solaris — failed mage protagonist; your decisions wear their name.
- Hom / Homu — homunculus partner; Trust is the mechanical and emotional hinge.
- Tetia — classmate route gravity.
- Croisé — maternal route gravity.
- August — shop and town economy face.
- Melchior — one of The Three; late implications without details here.
- Secret antagonist — present; discovery is part of the scenario.
Deeper bios belong on the Players Hub as that section expands. Ranking of skills and gear for combat-focused clears belongs on the Tier List Hub.
Demo, languages, and expectations
Steam languages include English, Japanese, Simplified Chinese, Traditional Chinese, and Korean — story nuance can differ slightly by localization, but the branch structure is shared. The demo (app 3400280) may not expose full ending space; treat it as systems practice. Full game achievement count (85) may include story exploration badges; chase them after you understand ceremony survival.

Frequently Asked Questions
Quick answers for Project Solaris players.
Does Project Solaris have multiple endings?
Yes. Endings form from choices, milestones, and side stories across the 100-day campaign, not from a single toggle.
Will this page spoil the story?
No. It explains branch inputs and safe hunting methods without naming twist outcomes or exact route flags.
Do I need high Trust for endings?
Trust helps both hard QTEs and relationship-facing routes. Ignoring Social can close branches even if combat is strong.
Can I see every ending in one run?
Plan on multiple saves. Focus different cast side stories after a first mechanical clear.
Where should I go for character details?
Use the Players hub for roster context. Use 100-Day Strategy to keep milestones alive while you pursue side stories.
