How to Play BOMBANANA!: Full Game & Co-op Lobby Guide

Getting started with BOMBANANA! requires three willing friends, working microphones, and a shared tolerance for hilarious misunderstandings. Following the official Steam launch on September 2, 2026 by Lefto Studio and TARK, squads now have access to the complete 30-level Campaign, Endless survival waves, and Custom sandbox rooms.

Because the game relies on strict asymmetric sensory limitations, setting up your lobby and audio settings properly before the countdown starts is crucial.

Here is the complete walkthrough for launching the full Steam release and completing your squad’s first successful defusal.

1. Getting the Full Game on Steam

BOMBANANA! is available directly on Valve’s Steam store platform:

1. Open your Steam client and search for “BOMBANANA!” (Steam Store App ID: 4656000).
2. Purchase and install the full release (approximately 1.8 GB disk footprint).
3. Ensure all three squad members have the game updated to the latest Steam build before launching private lobbies.

2. Setting Up an Online 3-Player Co-op Lobby

+-------------------------------------------------------------+

1. Host Creates Lobby: Select Play Co-op ➔ Host Private Squad.
2. Invite Teammates: Press Shift + Tab to open the Steam Friends Overlay and send game invites to your two partners.
3. Assign Monkey Roles: In the minivan pre-game lobby, each player must click on their preferred seat to lock in their role:
   • Player A: Blind Monkey (Steering wheel seat — handles all physical bomb interactions)
   • Player B: Mute Monkey (Manual desk seat — holds the complete 30-level defusal manual)
   • Player C: Deaf Monkey (Observation hatch seat — sees the bomb, directs Blind via voice)

3. Pre-Flight Audio & Microphone Configuration

Because the game simulates deafness and muteness programmatically, your squad must coordinate their voice chat software:

• In-Game Voice Chat: BOMBANANA! features built-in directional proximity audio. The game automatically mutes Mute Monkey’s microphone and silences all incoming audio streams for Deaf Monkey.
• Third-Party Voice (Discord / Teamspeak): If your group is using Discord, Deaf Monkey must deafen themselves (Ctrl + Shift + D), and Mute Monkey must mute their microphone (Ctrl + Shift + M). This preserves the intended asymmetric challenge.

4. Full Campaign Level Progression (30 Levels)

The full commercial release expands far beyond the introductory stages:

Level Bracket	Environment & Workshop	Core Threat & Modules	Difficulty Grade

Levels 6 – 12	Highway Pursuit	4–5 Wires, Ancient Runes, ticking sirens	Intermediate

5. First Run Survival Checklist

Before launching Campaign Level 1, confirm these five checks with your squad:

• Role Handshake: Confirm who holds the manual (Mute) and who has voice authority (Deaf).
• Emote Wheel Binding: Mute Monkey tests mouse gesture radial controls (Q key by default).
• Slap Test: Each player executes a test slap on their teammates to ensure responsive hitboxes.
• Timer Awareness: Locate the central digital countdown clock on the bomb casing.
• Strike Counter: Locate the red cross strike indicators; 3 strikes means detonation!
