Inventory first
Prepare Symbol, Piano before the 4:00 timer starts.
Level 10 gives the squad 4:00, allows 3 mistakes, and combines Symbol + Piano with Alarm CHAOS.
Use this page as a Level 10 solution plan: confirm the exact setup, assign CHAOS ownership, then work through the named procedures before improvising around random slots.
Read the timer, mistake limit, and listed defusal modules before pressing any panel.
Open each named module guide and assign one player to any CHAOS duty.
Resolve one clue packet at a time, then use Previous Level and Next Level navigation for campaign practice.
Medium modules now compete with one or more CHAOS tasks. Preserve a single conversation lane: one clue packet, one answer, one confirmation.
The named defusal panels can be prepared in advance; open their procedures before the timer begins. Keep one player responsible for Alarm while the other two maintain the main clue-answer loop.
Campaign composition, timer, and mistake allowance were cross-checked against the public BOMBANANA v1.0.0 level reference.
Prepare Symbol, Piano before the 4:00 timer starts.
Symbol: STAGE → SOUNDING SYMBOL → REQUIRED COLOR · Piano: OCTAVE → LIGHT COLOR → NOTE SEQUENCE
Alarm: When active, press every heated button within 10 seconds.
This plan is derived from the verified v1.0.0 level composition and the named module procedures. Random slots are intentionally not converted into fixed answers.

Level 10 fixes both Symbol and Piano while Alarm interrupts the solve. There is no universal best first module: choose one clue packet, keep Alarm ownership visible, and finish each manual lookup before opening the other.
Assign Alarm ownership before touching Symbol or Piano; clear every heated Alarm button when it activates.
Choose one active module and name it before calling clues so stage, color, and Braille data cannot cross.
For Piano, pair the Braille octave with the active light and return the four notes in order.
For Symbol, find the sounding symbol, report the current stage, and use the current manual for the required color.
After Alarm interrupts, restate the active module and its complete clue packet before continuing.
This walkthrough combines verified level composition with module procedures and avoids claiming one static live answer. Re-check lookup tables after a gameplay patch.
