Gunstoppable Loadout Helper

Gunstoppable asks you to wield two weapons at once, modify both through a hex attachment grid, and stack run-based augments until something breaks—in the fun way. There is no single permanent loadout: Kane the Rat refreshes options between floors, deaths unlock permanent upgrades, and augments can turn a shotgun into a flamethrower or bananas into tactical nukes. This helper is a decision framework so you pick fast, keep reloads staggered, and avoid upgrades that punish movement.

Read it before major shops or boss floors. Combine with Starter Builds for concrete openers, the Tier List for power spikes, and Movement and Momentum because slow loadouts fail even when DPS numbers look high on paper.

Core rules (always true)

1. Speed scales damage — attachments that encourage camping (long charge, stationary channel) need exceptional payoff or they belong in storage.
2. Dual-wield = reload management — one hand should fire while the other reloads. Overlapping empty magazines is the most common avoidable DPS loss.
3. Hex grid is run-local — prioritize slots that boost on-move effects first; luxury slots can wait until Kane offers a reroll or boss payout.
4. Augments redefine roles — a mid-tier weapon with explosive augment can outpace S-tier baseline for that run only. Re-evaluate after every augment offer.
5. Reaper Mode loves density — loadouts with moderate single-target and strong cleave activate kill chains faster. See Controls for Q/B timing.

Step 1 — Pick primary role

Choose what the right hand must solve in the next two floors. Mark one row.

Role	Solves	Weak when
Close burst	Rush elites, finish grappler targets	Snipers at range
Mid control	Stable DPS while moving	Pure bullet-hell walls
Long poke	Turrets, flying drones	Melee rush rooms
Crowd clear	Add waves before boss phase	Single-target bosses only
Melee hybrid	Parry setups, high impact frames	Open arenas with kiting

If the next gate is a named boss, read their hub entry and bias toward crowd clear or long poke depending on add spawns.

Step 2 — Pick secondary by reload cadence

Secondary exists to cover downtime, not duplicate primary weaknesses.

Primary reload	Best secondary cadence	Pairing goal
Fast	Medium or slow	Secondary fires during primary reload
Medium	Fast	Burst swap on elite spawn
Slow	Fast	Always have a bullet ready while moving
Melee primary	Fast ranged	Never stand still for reload in melee range

Sample pairing matrix (launch era)

Use as templates—not law. Augments can invert ranks overnight; verify against Patch Notes when weapons receive tuning.

Primary	Secondary	Synergy note
Shotgun (close burst)	Handgun (fast)	Flamethrower augment on shotgun + pistol cleanup
Katana (melee hybrid)	Crossbow (long poke)	Parry into off-hand bolt; matches demo marketing combos
Banana launcher (crowd clear)	Knife (fast melee)	Demo Patch 24 buffed banana gun—cleave then finish
Rocket launcher (slow)	SMG-style fast gun	Swap on reload; rocket for Reaper clumps
Flamethrower augment SG	Grapple-friendly pistol	Keep speed while DoT ticks

Full weapon names and attachment paths live on Starter Builds and the Tier List.

Step 3 — Attachment grid priorities

Attachments slot into a hex grid. When Kane offers multiple pieces, score them with this table before rarity hype.

Priority	Attachment theme	Why momentum players care
1	On-move proc	Damage that requires speed stays on multiplier
2	Reload speed / mag size	Shorter empty windows while grappling
3	Alternate fire mode	Bonus burst without stopping (e.g., under-barrel)
4	Elemental spread	Cleave for Reaper chains
5	Precision scope	Low priority unless sniper floor upcoming
6	Charge shot	Only if charge can slide-cancel or parry-cancel

Grid planning UI (mental model):

[ mobility slot ] — [ core dmg ] — [ reload ]
        \              |              /
         [ augment bridge slots ]

Fill mobility-adjacent slots first, then bridge toward augments that need adjacency bonuses. Exact hex shapes vary by weapon; treat the diagram as priority order, not literal layout.

Step 4 — Augment decision filter

When offered three augments, run each through MOVE filter:

Letter	Question	Pass example	Fail example
M	Must it be fired standing still?	Slide-shotgun pellets	Full-charge rail without cancel
O	Overlap with secondary role?	Explosive bananas + fast knife	Two slow reload primaries
V	Value during Reaper Mode?	On-kill splash	Single-target dot with no density
E	Enhances kill chain speed?	AoE on death	Delayed mine layer behind you

Pick the first augment that passes three of four letters. If none pass, choose least bad M failure and compensate with movement drills from the Momentum Checklist.

Step 5 — Boss and floor counters

Threat type	Shift primary toward	Keep secondary
Bullet hell CEO patterns	Mid control + dash routes	Fast cleanup gun
Melee rush / crab elites	Parry-friendly melee or shotgun	Ranged poke
Vertical arena	Grapple-stable mid AR	Long poke
Add-heavy phase	Crowd clear	Single-target boss DPS

Meta progression hooks

Permanent upgrades change which opener is viable. Before committing currency:

Meta purchase	Loadout impact
Opener speed boost	Favor slow weapons that scale hard once moving
Parry economy	Melee hybrid primaries rise in value
Shop discount	Can afford experimental pairs—test off-meta duos
Health vs speed	Low health pushes safer mid-control secondaries

Re-run Step 2 after any permanent upgrade that touches reload or shop prices.

Between-run reset checklist

Item	Action
Last run DPS issue	Reload overlap? Re-pick secondary cadence
Patch day	Re-read Patch Notes for weapon lines
New boss reached	Update Step 5 counter row
Comfort pair stale	Swap one weapon for Tier List riser

Common mistakes

• Double slow reload — feels powerful until both hands empty mid-grapple.
• Camping for charge shots — drops speed multiplier; DPS net negative.
• Ignoring augments that change role — keeping “shotgun secondary” when augment turned primary into flamethrower.
• Skipping Kane because of decision fatigue — use MOVE filter; indecision wastes more time than a wrong pick.
• Copying streamer pair without movement skill — high APM pairs assume Momentum Checklist mastery.
