UNATCO TRAINING MANUAL
Section 3C: Multitools
A "multitool" is not really a tool at all -- not in the usual sense of the word -- but a disposable electronic device that utilizes electromagnetic resonance detection and frequency modulation to dynamically alter the flow of current through almost any non-hardened circuitry. Skilled agents can use the multitool to manipulate code locks, cameras, autogun turrets, alarms, or other security elements.
Note that multitools CANNOT be used for computer information extraction (see Section 5A: Hacking).
