How to Play Gunstoppable

Gunstoppable is a momentum roguelite FPS from CAGE Studios where every run is a solo sprint through corporate hellscapes. Released on PC Steam August 5, 2026, with Xbox Series X|S following August 31, 2026, the game asks one question repeatedly: can you keep moving long enough to make your weapons matter? This guide explains the full run loop so you can stop guessing why Kane skipped you or why damage suddenly cratered mid-room.

If you have never launched the game, start with Getting Started for first-run habits. Keep Controls nearby for bindings while you read.

Run Structure Overview

Each Gunstoppable attempt follows a roguelite arc:

• Act opening — tutorialized combat or a soft intro biome.
• Branching paths — choose doors or map nodes leading to Underwater Prison, Cyberpunk City, or other zones detailed in Map & Biomes.
• Merchant beats — Kane the Rat sells gear between major encounters.
• Elite rooms — spike difficulty; test parries (Parry Guide) and speed upkeep.
• Boss gates — five capitalist bosses, including spectacle fights like Johnny Jetpack and the giant robot crab (Bosses).
• Run end — victory unlocks meta rewards; death ends the current build.

There is single-player only. Fenix carries every fight alone with full voice acting—performances from talent such as Gianni Matragrano and Neekolul flavor story beats, but mechanics stay arcade-sharp.

Speed and Damage

Gunstoppable’s central math ties movement speed to outgoing damage. Slow Fenix equals weak shots; chained grapples, slides, wall-runs, and rail-grinds multiply pain on the same trigger pull. Standing in cover like a traditional cover shooter will fail—you must orbit enemies while firing dual-wield setups.

Read Movement & Momentum for route examples. Practical rule: enter each room already moving; exit with speed banked for the next door.

Dual-Wield Loadouts

You juggle ten weapon identities across a run but equip two at a time. Weapons accept attachments (stat mods) and augments (hex-grid perks that can rewrite behavior). Absurd synergies are intentional—shotgun augments can become flamethrowers; banana lines can escalate toward nuke-like blasts.

Consult Weapons, Items, and the Tier List when planning purchases. Early runs favor consistent DPS pairs; late runs chase synergy breakpoints Kane offers.

Kane the Rat Economy

Kane shops are decision points. Currency comes from room clears, breakables, and optional challenges. Spending priorities shift by biome hazard—underwater slows momentum, so buying mobility augments before Underwater Prison deep dives saves deaths.

Typical shop flow:

1. Assess health and ammo.
2. Compare one weapon upgrade versus one augment that protects speed.
3. Fill attachment slots before chasing a third weapon type you cannot wield simultaneously.
4. Skip low-impact stat bumps if a boss gate icon is next.

Kane inventory refreshes between acts; patch changes on Updates sometimes add new augments—recheck Tools calculators after patches.

Reaper Mode in the Loop

Reaper Mode rewards aggressive kill chains by letting you slow time—but only after you press Q (keyboard) or B (controller). It is not automatic. Use Reaper to clean elite packs, stabilize bad engagements, or burst boss adds. Chain maintenance is covered in Reaper Mode; in the macro loop, treat Reaper as a resource you spend at Kane doors before entering known spike rooms.

Biome Choice Matters

Path selection is not cosmetic. Cyberpunk City emphasizes vertical wall-runs and grind rails—great for speed builders. Underwater Prison introduces drag and sight-line tricks—better once you understand parry windows and grapple shortcuts. The Map & Biomes hub compares hazards so you do not random-walk into a mismatch with your current augments.

Boss Gates and Win Conditions

Each capitalist boss exam tests a different skill:

• Movement routing — jetpack patterns and aerial phases.
• Add control — Reaper timing versus hand-clearing.
• Parry discipline — melee telegraphs during crab shell phases.

Study Bosses before committing consumables. Boss rooms rarely offer Kane visits mid-fight; arrive prepared.

Winning a full run means clearing the final executive encounter and watching the closing cinematic. Partial progress still teaches routes—roguelite repetition is the tutorial.

Scoring and Style

Gunstoppable tracks style through speed, air time, parries, and chain length. High scores unlock cosmetics or meta upgrades depending on current build version—verify on Updates because launch-month patches adjust rewards. Even if you ignore leaderboards, style meters feedback whether your movement is healthy.

Common Failure Points

• Zero speed openings — sprint and grapple before first shot.
• Ignoring Reaper prompt — press the button; see Reaper Mode.
• Misaligned augments — synergy pieces without base DPS; check Tier List.
• Under-gearing for bosses — shop before gates, not after wipes.
• Static reloads — reload on slides; see Movement & Momentum.
