Gunstoppable Items & Upgrades

Items in Gunstoppable split into two timelines: within-run pickups that reset on death, and metaprogression that makes the next Fenix broadcast stronger. Understanding both is how you break the five capitalist boss gates without grinding the same floor forever. This hub links every item-focused page — merchant stock, permanent trees, and roguelite modifiers — alongside Weapons, Tier List, and Guides loadout advice.

CAGE Studios built Gunstoppable as a momentum roguelite FPS: speed multiplies damage, dual-wield ten weapons with hex-grid augments, and Reaper Mode rewards kill chains. Items accelerate that loop — they do not replace movement skill from Controls.

Item categories

Merchant — Kane the Rat

Kane the Rat is the friendly black-market merchant who appears between major floors. He sells powers, augment rerolls, and utility that shape dual-wield builds before boss arenas. Fenix’s sister narrative ties into Kane’s role as an underground supplier opposing CEO war profits.

Deep dive: Kane the Rat.

Permanent upgrades

After each run ends — death or clear — you spend earned currency on permanent upgrades that persist forever: momentum caps, Reaper duration, reload trims, health-on-parry, Kane discount tiers, and more. This is the primary reason failed runs still feel productive.

Deep dive: Permanent Upgrades.

Run modifiers

Temporary run modifiers appear during floors as roguelite choices — often three-option picks like other roguelites. They buff damage types, movement, Reaper generation, or weapon-specific quirks until the run ends. Synergize with Builds Tier List archetypes.

Deep dive: Run Modifiers.

Weapon augments and attachments (in-run)

Fourteen attachments and twenty-four augments slot into hex grids on weapons themselves — turning shotguns into flamethrowers or bananas into nukes. These are item-like pickups but live on the Weapons system; Kane can reroll or sell related utilities.

Economy loop diagram

Floor combat → currency + modifiers → Kane shop → boss gate
       ↓ death
Permanent upgrades → stronger next run → repeat CEO assault

Single-player only — no shared stash or multiplayer drops.

Currencies (community naming)

Exact currency names appear in UI strings across English, French, German, and Spanish localizations. Wiki pages use descriptive labels until dataminers finalize terms:

• Run currency — drops during floors, spent at Kane same run
• Meta currency — awarded on run end, feeds permanent tree
• Bonus tokens — challenge or boss-clear rewards in some seeds

Update this hub when official terminology stabilizes post-launch patches.

Items vs tier lists

Tier lists rank weapons and builds assuming average augment access. Items shift those tiers — a B-tier grenade launcher becomes S-tier when Kane sells banana-nuke rerolls and a run modifier buffs explosive augments. Always re-evaluate after shopping.

Items make Fenix louder between runs. Movement still wins the broadcast.
