— Item examination - Japanese
The Detonator (起爆信管,kibaku shinkan?) is an item in Resident Evil CODE:Veronica that is found and used in the Chemical Weapons Storage Room at the Antarctic Base. The detonator is found near a corpse at the very end of the room, and placed into the ammo locker which is in front of that corpse.
The lighter is needed for detonation as it is sensitive to heat, to retrieve three boxes of handgun rounds.
