Marie's Adventure Steam Achievements (69)
Pregnancy milestones, brothel grinds, dungeon clears, and 100% completion roadmap.
Marie’s Adventure ships with 69 Steam achievements on app 4819360. Many trophies track the same systems this wiki already explains — pregnancy litter size, brothel sessions, companion skill mastery, and deep dungeon clears — so this page is a roadmap, not a spoiler dump of every story beat.
Steam global stats shortly after launch show early story achievements (for example A Journey Begins) unlocking for most players, while completionist trophies sit near 0.1%. Use that as a difficulty hint, not a leaderboard.
Early story and exploration
| Achievement | What it tracks | Wiki help |
|---|---|---|
| A Journey Begins | Start Marie’s adventure | Getting Started |
| The Talking Carrot? | Talk to Mandrake once | Explore NPCs early |
| The Three Goddesses Statue? | Enter Heritage plane first time | Heritage Plane |
| Into the Slums | Unlock the Slums | World Locations |
| Past the Due Date | Trigger Overdue first time | Stay pregnant and keep walking |
Keep talking to odd NPCs — Mandrake and similar flavor characters often hide first-time flags.
Pregnancy and birth trophies
Litter achievements line up with milk-capacity math from the pregnancy system:
| Achievement | Goal |
|---|---|
| Whoa! There’s Two! | Conceive twins |
| Wait, There’s Three?! | Conceive triplets |
| What Did You Say? Four?! | Conceive quadruplets |
| Five?! For Real?! | Conceive quintuplets |
| You’re Pushing Your Luck Too Far | Trigger Forced Birth |
| That’s a Lot of Babies! | Give birth to 100 babies |
Prep at the Church, equip fertility gear from fertility boosts, then save-scum after conception using how to get multiples. Remember: walking advances pregnancy; sleeping alone does not. Deliver only at Sylva City Inn.
The pregnancy tracker converts milk capacity (300 / +50) into litter estimates while you hunt rare rolls.
Brothel and lewdness
| Achievement | Goal |
|---|---|
| Nice. | Conduct 69 brothel sessions |
| Client Spotter | Unlock every unique client |
| Uninhibited | Max every character’s Lewdness Level |
| What Just Happened? | Get Intoxicated during a session |
| Too Much of a Good Thing | Get Overdosed once |
Brothel routing lives on the brothel guide. Companion lewdness tracks separately for Marie, Elucia, and Ran — see companions.
Combat and dungeon clears
| Achievement | Goal |
|---|---|
| Demon Hunter | Slay 100 demons |
| Demon May Cry | Slay 666 demons |
| ALTOMYOSTR Explorer / Delver / Conqueror / Master | Finish floors F1–F4 |
| Escape Artist | Survive a tough escape scenario |
ALTOMYOSTR is a late multi-floor challenge — full routing tips live on the ALTOMYOSTR build guide. Treat each floor clear as its own session with saves before bosses. Combat fundamentals: combat basics.
Companion mastery and collections
| Achievement | Goal |
|---|---|
| Magecrafter Madame Marie | Learn every Marie skill |
| E in Excalibur stand for “Elucia” | Learn every Elucia skill |

Artifact upgrades and treasure hunting pair with artifacts and world locations. Ran unlocks in Chapter 2 — you cannot finish her skill tree before she joins.
Wealth and lifestyle
Filthy Rich asks for 10,000,000 monies. Brothel shifts, treasure routes, and post-birth combat efficiency all feed the grind. Smokin’ Sexy Style! wants SSS talent rank — treat it as a long-term build goal beside party progression.
Practical completion tips
- Separate save slots for multiples hunting versus story progression.
- Whitelist Defender so collection flags are not lost to deleted files (troubleshooting).
- Toggle content settings only after you understand which scenes you still need for Client Spotter and story trophies.
- Do not expect itch/DLsite installs to unlock Steam achievements — trophies are Steam-only.

- How to Get Multiples — twins through quintuplets.
- Brothel Guide — session grinding.
- Known Issues — loops that can soft-lock scene trophies.
Sixty-nine trophies sound meme-heavy until you hit the 100-birth and ALTOMYOSTR stack — plan the pregnancy engine first, then chase collections.
