BOMBANANA! Wiki & Guide

The player-made reference for the chaotic 3-player bomb-defusal co-op by Lefto Studio.

BOMBANANA! is a chaotic co-op game for exactly three players, each holding only part of the information: the blind monkey can touch the bomb but not see colours, the mute monkey can read the bomb manual but not speak, and the deaf monkey can see everything but hears nothing. Defuse the bomb together — or go BOOM! This unofficial fan wiki collects the manual reference, module notes, roles, campaign levels and problem-focused walkthrough help, with every claim labelled by how sure we are.

BOMBANANA! by Lefto Studio is an explosively funny three-player co-op bomb-defusal game. Each player has only part of the needed information, so communication is the whole game: wave, shout, gesture, throw bananas — the developers deliberately impose no method. The game launched September 2, 2026 and grew to 500,000+ players in its first week with a 97% Overwhelmingly Positive Steam rating.

The core loop

  • One bomb, three monkeys, one manual. The mute monkey is the only player who can read the bomb disposal manual — and cannot tell anyone what it says. Read the manual hub.
  • Information is deliberately split. The blind monkey can feel the bomb but cannot see colours or screens; the deaf monkey sees everything but hears nothing. Roles explained.
  • Communication beats guessing. Every module needs a report: state in, confirmed action out. Until a module's exact rules are confirmed, guides here say so instead of inventing answers. Modules overview.
  • Pick a mode. Work through 30 handcrafted campaign levels, survive endless procedural waves, or build your own nightmare in Custom. Levels & modes.

What is confirmed vs not

Confirmed on the official store page and developer news: the three roles and their abilities, the manual as the mute monkey's only tool, three game modes (Campaign — 30 handcrafted levels, Endless — procedurally generated waves, Custom — tune bomb difficulty, explosion timer, module types, hazards and mistake limit), 14 puzzle modules in the full release (11 standard + 3 CHAOS “designed to keep the Blind Monkey busy”), environmental hazards (power outages, loud noises), colourblind mode and Steam Achievements. Not yet confirmed: the exact wiring of any individual module, the specific layout of any campaign level (including Level 5), and the achievement list — none of that is officially published, so this wiki labels it clearly instead of guessing.

v1.0.1 hotfix (voice chat fixes, Spanish Yes/No placement) shipped shortly after launch; known issues: occasional random crashes under investigation by the developer. Source: official news.
