Starbreed 100% Completion Route
One spoiler-light plan for all 22 Steam achievements
Scope
Starbreed’s Steam page lists 22 achievements. You cannot unlock every icon in a single uninterrupted story pass—plan for replays, Affinity grinding, Brothel reputation, Data Chips, Impregnation Trials, and multiple Endings flags. This route is the wiki’s completion spine after the July 30, 2026 release (Steam app 2694020, itch v1.0.2 packages). Adult scenes stay described as unlock flags only.
Pair this page with Achievements for spoiler-light icon names, Data Chip Locations for stage verbs, Trial Scores for gold numbers, and Finale2 for the Nova rush.
Phase 0 — Foundation
- Finish a comfortable first clear of early planets using Getting Started and Controls.
- Spend Credits on combat tools, not pinups (Credits Shop).
- Start dumping mission points into Assertion and Resolve under the Aether tab (Resolve and Assertion).
- Unlock Female Aether at Resolve ~50 before Brothel work (Aether, Brothel).
- Keep Affinity Checklist open from the first hub night.
Campaign clears will naturally pop progress icons such as All Bark! (Nova in Catiya 2), You’re Next, Nova! (Finale1), and Conqueror (all main levels).
Phase 1 — Stat and ending prep
Push these numbers while farming missions:
| Stat | Target | Why |
|---|---|---|
| Assertion | 100 | King of Catiya / Royalty ending flag |
| Resolve | 50 | Female Aether + Brothel access |
| Resolve | 100 | A Better Life / Brothel ending flag |
| Brothel reputation | 100 | True Calling |
After Finale2, dialogue tone plus prepared stats select endings:
- Assertion 100 + merciful tone → King of Catiya
- Invite Nova to the crew + merciful tone → Family Man
- Resolve 100 + justice tone → A Better Life
- Missing those conditions → Peace Restored
Replay Finale2 as Nova at least once for Supernova. Who Am I? wants both Assertion and Resolve at 100+.
Phase 2 — Affinity, Trials, medals
Raise every romance ally to 100 Affinity for My Harem, then run Trials:
| Trial | Gold |
|---|---|
| Nova | 32 |
| Lana / Nika / Tanya | 210 |
| Siren | 245 |
| Pix | 270 |
| Rooster | 300 |
Hits cost 10; two hits usually dump gold. Full tactics: Impregnation Trials and Trial Scores. Silver on all Trials → Master Of Starbreed; Gold on all → God Of Starbreed. Stage medals (Bronze / Silver / Gold on all main levels) are separate—see Medals and Scoring for Bronze / Silver / Gold Pilot.
Phase 3 — Data Chips and Pom flags
Hunt every chip with Data Chip Locations. Save Catiya 2 (60s Nova) and Finale 1 No Help for a fully upgraded Neural Link shell.
- Knowledge Is Power — all chips
- 4 chips — Aether-screen clone option → I Am The Captain Now!
- 11 chips — Pom H-scene menu action → The Future Is Now!
- Combine Pom flag + Nova breeding path + all Trials → StarBREED
Phase 4 — Brothel mop and Tanya buyout
As Female Aether, clear Brothel Room requirements for Paternity Test (track the listed male models plus clone / ridable checks described on Brothel and Achievements). Max reputation for True Calling.
Top Customer (buy out Tanya’s Cyber Shop) wants: Gold medals on all missions, all Data Chips, max Brothel reputation, and max Affinity for all crew. Excess Affinity and unused Brothel stamina convert into Credits; Neural Link keeps Tanya’s passive online. Farm a few easy missions if the wallet is short.
Suggested calendar
| Block | Focus |
|---|---|
| Nights 1–3 | Story clear, Assertion/Resolve investment, early Affinity |
| Nights 4–6 | Mid planet medals, shop weapons, Female Aether |
| Nights 7–9 | Finale2 + ending replays |
| Nights 10–12 | Chip verbs + hard timer chips |
| Nights 13–15 | Trials gold, Brothel, Tanya buyout |
What not to mix
Do not chip-hunt during a blind boss. Do not Trial three EX passives the same night you attempt Finale2. Do not buy pinups before Neural Link if you still lack timer-chip DPS. Do not treat demo footage as 1.0 chip truth—see Demo vs Full.

Sanity check before you call it done
Open Steam’s achievement list beside this route. Every locked icon should map to a phase above. If an icon remains after buyout, chips, Trials, endings, and Brothel, re-read the spoiler-light hint on Achievements—do not invent a sixth system. Starbreed’s 100% is long, not mysterious once the five pillars (campaign, stats, Affinity/Trials, chips, Brothel/shop) are scheduled.
