Gunstoppable Steam Achievements Guide

Gunstoppable ships on Steam with 21 achievements listed on the store page at the August 5, 2026 launch. CAGE Studios does not publish a separate in-wiki trophy spreadsheet, and achievement names can differ between demo builds and the full campaign. This guide groups every unlock into plausible goal categories—progression, combat, movement, bosses, and completion—so you chase habits instead of guessing exact Steam API strings.

Treat achievements as a training syllabus: they nudge you toward the same skills that keep leaderboard scores high and Reaper Mode chains alive. Single-player only; single-player only or shared unlock tricks.

What we know at launch

Fact	Detail
Platform	Steam (PC) at 1.0; Xbox Series August 31, 2026
Count	21 achievements on the Steam store page
Tracking	Steam overlay and profile; no in-game trophy room required
Difficulty mix	Expect skill checks, story milestones, and build variety

We do not list fabricated official achievement titles here. When Steam community guides confirm exact names, cross-check your profile popup against the category tables below.

Category map (21 goals)

Steam achievement sets for momentum roguelites usually split like this. Gunstoppable’s demo patches already rewarded parry mastery, speed routes, and weapon variety—full release likely extends those themes.

Category	Typical goal style	Estimated count	Wiki focus
Campaign progression	Beat floors, biomes, or story beats	4–6	Getting Started, Campaign Walkthrough
Boss milestones	Defeat named billionaires or phase gates	3–5	Bosses, Johnny Jetpack, Robot Crab
Movement mastery	Maintain speed, chain verbs, or finish routes fast	4–6	Movement and Momentum, Momentum Checklist
Combat variety	Parry streaks, dual-wield kills, Reaper clusters	4–6	Parry, Dual-Wield Combos
Completion / meta	Full runs, upgrade tiers, or collection	2–4	Permanent Upgrades, Kane the Rat

Numbers are illustrative buckets totaling 21—not confirmed per-category quotas from CAGE Studios.

Progression and story achievements

Story-linked unlocks usually fire when Fenix clears major biomes: Underwater Prison, Cyberpunk City, and late billionaire arenas. Demo Patch 25 moved the public demo entry into underwater prison—if you only played the old slice, expect fresh routing on a return visit.

Approach:

1. Play the campaign in order on normal difficulty first; speed goals come later.
2. Use Save Anytime if offered in your build—accessibility settings do not disable Steam tracking for standard story flags.
3. Read Launch Notes for language and platform parity before grinding on a second PC profile.

Common failure mode: Rushing shops at Kane the Rat without buying opener upgrades. Meta spend that boosts first-room speed prevents soft-lock feelings on progression gates.

Boss and encounter achievements

Boss buckets reward first kills, no-hit variants, or phase-specific tech. Gunstoppable’s roster mixes bullet hell, melee rush, and arena denial—see Bosses Overview for telegraphs.

Habit	Why it matters for boss trophies
Manual Reaper on Q/B	Patch 24 removed automatic slow time—burst during add waves, not after cleanup
Parry impact frames	Patch 24 rework; old demo timing whiffs on melee bosses
Elite markers	Patch 24 UI labels last 1–2 enemies—plan Reaper before overkill
Corpse grapple	Patch 25 ragdoll hooks for vertical repositioning in tower fights

Space tower rework and spider bot variant from Patch 24 signal that encounter layouts change between builds. If an achievement references a tower or spider encounter, verify you are on the current app version—not an outdated demo install.

Movement and speed achievements

Movement trophies are where Gunstoppable’s identity shines. Speed equals damage, and several achievements likely require you to finish rooms or floors while the speedometer stays high.

Post–Next Fest feedback added speed storage after wall collisions—hitting geometry no longer zeroes momentum the way earliest demos did. That change matters for wall-run routes documented in Movement and Momentum:

• Slide into walls at shallow angles instead of dead stops.
• Chain grapple exits into rail-grinds where Map Biomes provide rails.
• Glance at the speedometer HUD added in Patch 25 whenever DPS feels low despite good aim.

Run the Momentum Checklist before achievement sessions. Sections B and D directly target speed uptime and corpse grapple reliability.

Combat, parry, and Reaper achievements

Combat categories usually include parry counts, dual-wield kill thresholds, or Reaper activation during dense packs. Align with demo tuning:

System	Patch note	Achievement habit
Parry	Patch 24 impact frames	Practice on telegraphed melee, not contact spam
Banana gun	Patch 24 buff	Crowd clear for multikill thresholds—Tier List
Katana / knife	Patch 24 tune	Melee hybrid without stopping—Starter Builds
Reaper Mode	Manual Q/B since Patch 24	Activate at cluster peak—Controls

Dual-wield achievements punish overlapping reloads. Plan pairs in the Loadout Helper so one hand always fires while the other reloads.

Completion, collection, and meta achievements

Late-game buckets may require:

• Purchasing specific permanent upgrades tiers
• Filling hex attachments and augments grids across runs
• Clearing a full roguelite loop without abandoning mid-floor

Use Playable Without Timed Input if a trophy demands perfect parry strings but your reflexes need breathing room—timed parry windows still exist, but menu and shop inputs are not forced under countdown pressure on supported settings.

Suggested achievement route (launch week)

Phase	Focus	Pages
1	Story + controls muscle memory	Getting Started, Controls
2	Movement speed habits	Momentum Checklist, Movement and Momentum
3	Boss first clears	Bosses, Campaign Walkthrough
4	Score and speed polish	Leaderboards, Patch Notes
5	Cleanup / missables	Items, Weapons variety runs

Demo vs full game tracking

The free Steam demo and full app (store ID 3724710) maintain separate achievement sets. Demo Patch 25 reset leaderboards when the underwater prison slice replaced older routing; full-game achievements start clean at 1.0. Verify you launched the purchased build if progression trophies fail to pop.

Accessibility and achievement hunting

Gunstoppable lists several comfort options on Steam—full controller support, camera comfort, color alternatives, custom volume with separate dialogue slider (Patch 25), playable without timed input, and save anytime. None of these inherently block standard achievement unlocks on Steam, but always read the pop-up when starting a run if CAGE adds optional challenge modifiers later.

Details live on Accessibility Settings.

After launch patches

When Patch Notes document balance changes, revisit combat and movement rows before blaming a “bugged” trophy. Weapon buffs (banana gun) and parry frame tweaks directly shift multikill feasibility.
