Gunstoppable Bosses
Five billionaire warmongers, one momentum-fueled Fenix — learn every phase before you livestream the takedown.
Gunstoppable’s campaign sends Fenix — the gladiator-turned-killing machine voiced in a fully acted story — through underwater prisons, cyberpunk cityscapes, and orbital excess to dismantle the capitalist architects of endless war. Along the way you clash with five major capitalist bosses, each guarding a slice of the CEO’s empire. Boss fights reward the same skill loop as the rest of the roguelite: build speed, multiply damage, chain kills into Reaper Mode, and dual-wield through bullet-hell patterns without standing still.
This hub links every boss page on the wiki. Use it alongside Guides, Weapons, Tier List, and Items when preparing loadouts.
How boss fights work
Unlike standard arena shooters, Gunstoppable bosses inherit the momentum rules:
- Speed still scales damage — slow players see longer time-to-kill even when patterns are memorized.
- Dual-wield stagger matters — reload one hand while firing the other during vulnerable windows.
- Reaper Mode is phase insurance — save freeze windows for add waves or telegraphed burst phases.
- Parries open melee routes — katanas and knives shine when bosses expose melee hitboxes between volleys.
Death sends you back to the roguelite loop, but permanent upgrades and Kane the Rat stock persist between runs. Boss knowledge carries too — learn patterns once, execute faster on reruns.
The five capitalist bosses
CAGE Studios pitches the campaign as a one-way capitalist-toppling trip. Five primary executives and war profiteers anchor major encounters — each with distinct arenas, add spawns, and movement checks. Exact naming varies in marketing copy (nepo babies, warlords, CEOs), but community guides group them as five capitalist boss gates before the finale.

Featured boss guides
Robot Crab
The giant robot crab is many players’ first major wall. Missile salvos and wide hitboxes look intimidating, but launch reviews share a consistent tip: control high ground so projectiles strike ceiling geometry instead of your hitbox. Pair with piercing or mid-range early-game loadouts.
Johnny Jetpack
A narcissistic aerial legend from the marketing campaign — jetpack mobility, fame-hungry taunts, and vertical bullet patterns. Favor tracking weapons and Reaper bursts when he hovers for camera poses.
Campaign Walkthrough
Floor-by-floor route through all boss gates, including Reaper timing and shop stops at Kane. Includes embedded official demo footage for visual learners.
Enemies
Add families between boss gates—mechanized militia, drones, winged assassins, spider bots from Patch 24, nepo babies, and crab set-pieces. Learn kiting, parry windows, and momentum counters before Johnny Jetpack or the CEO finale.
Recommended prep by system
| System | Before any boss | Resource |
|---|---|---|
| Movement | Grapple, slide, wall-run chains | Controls |
| Loadout | Dual-wield pair + augment plan | Builds Tier List |
| Economy | Kane purchases, currencies | Items Hub |
| Burst windows | Reaper Mode execution | Guides |
Boss difficulty community notes
Early reviews note a split: standard enemy density kills runs more often than bosses once patterns are learned. That does not mean bosses are trivial — it means movement mastery flips outcomes faster than raw DPS checks. The robot crab is the teaching fight for arena positioning; Johnny Jetpack tests vertical aim; later CEOs stack add waves with shield phases.
If you stall, revisit Weapons Tier List and invest permanent upgrades instead of muscling the same under-leveled build.
Voice cast and tone
The campaign is fully voiced, featuring Gianni Matragrano (known from ULTRAKILL) and streamer Neekolul among others. Boss banter leans satirical — billionaire meltdowns, livestream metrics, and over-the-top villain monologues. Tone matches the absurd weapon augments (bananas as tactical nukes) documented on Run Modifiers.
