Quasimorph Steam Achievements Guide

Quasimorph version 1.0 launched on Steam July 31, 2026 with 82 Steam achievements covering clean extracts, storyline completion, class mastery, Magnum progression, and Quasimorphosis hardship. Magnum Scriptum also warns that console commands invalidate saves for achievements — a hard rule achievement hunters must respect before enabling debug habits from older Early Access advice.

This page is a routing guide, not a spoiled checklist of every secret epilogue line. Use it with Patch 1.0 Release Notes, the Walkthrough Hub, and Nine Endings Guide when trophies gate on narrative branches.

Achievement categories at launch

Community and patch messaging cluster the 82 trophies into practical buckets:

Extraction and survival — successful extracts, Defence timers, multi-floor clears, and low-death streaks. Fundamentals live in Getting Started and Room Clearing.

Combat and gear — damage-type mastery, weapon families, and midgame habits from Midgame Combat and Weapons. Gas grenades, deployable covers, and thrown weapons added in 1.0 expand challenge trophies.

Classes and operators — unlock and perform with starter and advanced classes. Track builds via Classes Hub and Tier List.

Magnum and economy — department unlocks, barter milestones, Trade Shuttle logistics in Trade Shuttle Guide, and Pact Department exchanges in Pacts and Skull Mechanics.

Horror and bosses — Quasimorphosis sectors, Rapture pressure, and Baron fights. Prep with Quasimorphosis Survival and How to Beat Baron.

Storyline and endings — arc completion and epilogue trophies across Civil Resistance, Tezctlan, Xiomara, AnCom, and RealWare. Structure without spoilers: Campaign Overview and Endings.

Console commands and invalid saves

If you open the console and run commands on a save, that save becomes invalid for achievements. There is no wiki workaround. Keep a clean achievement campaign separate from experimental console saves.

Related hygiene:

• Prefer vanilla or carefully vetted Map Packs — see Map Editor and Mod Manager.
• Backup %USERPROFILE%\AppData\LocalLow\Magnum Scriptum\Quasimorph\ before branch or mod experiments.
• Remember default Early Access saves already fail 1.0 compatibility; start fresh for trophy hunting.

First-week trophy route

1. Certify on Mars / Phobos / Deimos — Absentia moons with no Quasimorphosis for safe extract trophies.
2. Learn stances and doors — Combat Stances prevent the cheap deaths that reset streak achievements.
3. Unlock Magnum baselines — Navigation, Supply, Research from Magnum Ship Guide.
4. Pick Civil Resistance or Tezctlan — gentler first arcs for storyline trophies.
5. Delay hard horror trophies until dual-damage kits and meter tools are automatic.
6. Plan ending trophies last — multi-ending arcs (AnCom, RealWare) need branch saves or second runs.

Horror-gated achievements

Several hardship trophies expect non-Absentia stations. Do not grind them on day-one clones:

• Pack meter reducers and dual damage types.
• Prefer Defence, Control, or Security mission types when you need story progress with locked meters — Mission Types.
• For Baron-related trophies, clear the floor first, then manage Rapture intentionally per How to Beat Baron.

Dying with a story item still forces re-runs — achievements do not override permadeath.

Storyline and ending trophies without spoilers

Ending achievements track completion states, not wiki spoilers. Principles:

• Finish certification before flagging storyline contracts.
• Extract quest items immediately to ship storage.
• Watch multi-faction standing on Xiomara before irreversible forks.
• Expect AnCom and RealWare to each contribute two ending lanes inside the nine-ending set.

If a trophy stays locked after credits, you likely finished a different epilogue lane — check Endings structure and replay the missing branch.

Economy trophies and the Trade Shuttle

1.0’s reworked Trade Shuttle and Pact Department create new progression milestones. Sell-for-reputation mode can unblock faction-tied trophies faster than combat alone, but never liquidate rite materials needed for pact or ending prep.

Common achievement mistakes

• Using console commands on the only campaign save.
• Enabling conflicting Map Packs during story trophies.
• Hunting Baron achievements before learning meter tools.
• Expecting one save to collect all nine ending trophies without replays.
• Ignoring Q3 hotfix notes when a trophy trigger looks broken — check Updates Hub.

Eighty-two achievements reward disciplined Magnum loops as much as rare secrets. Keep a clean save, route storylines deliberately, and treat horror trophies as midgame content — not tutorial homework.
