ID Tag System


In the Big Shell, Raiden was unable to capture and use enemy weapons. This was because all weapons at the time were ID-tagged, equipped with personal identification devices. ID guns are programmed with identity data both during the firearm registration process and at the beginning of an operation, and the gun will not respond if anyone other than the registered user pulls the trigger. To use weapons in the Big Shell, Raiden had to search for "naked guns" without ID tags.
