Gunstoppable Momentum Checklist

Gunstoppable ties outgoing damage to movement speed. Fenix hits hardest while sliding into a grapple, wall-running out of a parry, or rail-grinding across an arena—not while repositioning on foot between cover nodes. This checklist is a practical pre-run ritual: verify settings, rehearse chains, and enter each floor with parry and Reaper Mode habits already loaded.

Print it, keep it on a second monitor, or skim once before clicking Ready. Pair with Movement and Momentum for route diagrams and Controls for exact bindings. If you are still learning weapon basics, glance at Starter Builds after movement rows pass.

How to use this page

Work top to bottom. Each section ends with a Go / Fix gate: if any row fails in the practice lane or first room, stop and drill that row before pushing Kane the Rat shops on higher floors. Roguelite runs forgive death, but they rarely forgive standing still during upgrade screens.

Section	Time	Purpose
A. Session setup	30 sec	Audio, performance, input
B. Movement chain	60 sec	Speed multiplier uptime
C. Parry and defense	45 sec	Impact frames and spacing
D. Grapple chains	45 sec	Height and corpse momentum
E. Offense and Reaper	30 sec	Dual-wield rhythm and slow time

A. Session setup

Check	Pass criteria	If fail
Dialogue volume split	Voice lines audible over combat SFX	Adjust dialogue slider separately (added in demo Patch 25 UX pass)
Speedometer visible	HUD shows current speed tier	Toggle HUD options before run
Reaper binding confirmed	Q (KB) / B (pad) triggers slow time on demand	Re-read Controls; slow time is not automatic post Patch 24
Performance headroom	Stable frame rate in busy rooms	Enable low graphics mode on minimum spec PCs
Input buffer feel	Slide and jump accept inputs during landing anim	Lower sensitivity or retry; Patch 25 added juicier jump/land feedback

Gate: All rows pass.

B. Movement chain (speed = damage)

Goal: enter the first combat room already above baseline speed. Standing start wastes the multiplier that makes tier list weapons feel S-tier.

Check	Pass criteria	Drill
Slide entry	Slide begins within one second of sprint	Loop slide → jump in empty corridor
Wall-run exit	Jump off wall with forward camera	See Movement and Momentum corner routes
Rail handoff	Mount rail without full stop	Practice approach angle from demo city block
Dash spacing	Dash covers gap without overshooting ledge	Mark floor tiles mentally
Speedometer glance	You notice speed drop within half a second	Watch meter during intentional pause

Chain template: sprint → slide → jump → wall-run → grapple → rail → slide. Shorten if arena layout denies rails.

Gate: Complete chain twice without dropping to walking speed between nodes.

C. Parry and defense

Demo Patch 24 reworked parry impact frames and melee animations. Old muscle memory from early demos may be early; trust the new window.

Check	Pass criteria	Notes
Impact frame timing	Parry connects on telegraphed melee windup, not contact	Listen for distinct parry confirm sound
Bullet-hell choice	You know when to parry vs dash	Elites with sustained fire favor dash + grapple
Post-parry reposition	Immediate slide or grapple, not strafe	Speed must rebound instantly
Melee follow-through	Knife or katana swing does not cancel momentum	Pair with dual-wield off-hand ready
Elite markers	Notice UI markers when 1–2 enemies remain	Added in Patch 24 for cleanup pacing

Gate: Three successful parries in practice or first wave without eating full damage.

D. Grapple chains

Patch 25 improved ragdoll launches and corpse grapples; Patch 24 reduced float on grapple and slide. Chains should feel snappy, not hang in air.

Check	Pass criteria	Common mistake
Hook priority	Grapple to high anchor before floor fight	Hooking floor enemies too early
Corpse grapple	Kill launches body; hook before it settles	Hooking late loses vertical speed
Slide under hook	Slide maintains horizontal speed entering hook	Standing hook
Ceiling clearance	Hook path avoids beam collision	Losing seconds to re-hook
Exit velocity	Release toward next enemy cluster	Hanging for full HP pick-up (move while looting)

Cross-reference boss arenas on Bosses—some billionaire fights deny long hooks until phase two.

Gate: One vertical grapple chain plus one corpse grapple in the opening encounter.

E. Offense and Reaper Mode

Reaper Mode slows time after sufficient kill chain buildup. Manual activation lets you burst during dense packs instead of wasting slow time on the last straggler.

Check	Pass criteria	Link
Dual-wield alternation	Off-hand fires during primary reload	Loadout Helper cadence table
Simultaneous burst	Both triggers on fat targets only	Avoid full double reload empty
Reaper trigger	Press Q/B at cluster peak, not empty room	Movement and Momentum kill chain notes
Reaper exit	Grapple planned before slow time ends	Prevents speed collapse
Boss threshold	Save Reaper for add wave or phase swap	See Bosses telegraphs

Gate: Activate Reaper at least once before first mini-boss or floor gate.

Between-floor mini checklist (15 sec)

Check	Action
Speed habit	Did last room end on slide or grapple?
Parry confidence	Any unexplained hits? Re-read telegraph
Weapon sync	Reloads still staggered? Adjust at Kane via Loadout Helper
Meta spend	Permanent upgrades that boost opener speed purchased?

Failure diagnosis

Symptom	Likely cause	Fix
Low DPS, good aim	Walking between packs	Repeat section B
Random deaths to melee	Early parry	Repeat section C with Patch 24 timing
Lost verticality	Late corpse hooks	Repeat section D
Reaper feels useless	Late activation	Press earlier on second enemy in cluster
Build feels weak	Wrong pair, not wrong skill	Starter Builds + Tier List

Patch awareness

Track live changes on Patch Notes. Movement feel, parry frames, and Reaper input shifted during demo Next Fest—this checklist reflects August 2026 launch-era behavior. After major patches, re-run section A and C first.
