A compact contact stun device the size of a cigarette lighter, delivering a 50,000-volt low-amperage electrical discharge through two prong electrodes on the business end. The MT-2 is the most basic stun device available in GLMZ — press it against an attacker, press the button, and the electrical discharge causes involuntary muscle contraction and immediate pain. The low amperage means it is unlikely to cause cardiac events in healthy individuals, though VoltLine's documentation includes the standard disclaimers about pre-existing conditions.

VoltLine manufactures the MT-2 in a facility in Tier 2 using largely automated production, keeping costs low enough that the device retails for Φ35. It recharges via standard micro-cell, and a full charge provides approximately thirty discharges. The device is available in a range of colors and finishes, from utilitarian black to bright patterns — VoltLine recognized early that self-defense devices that people actually carry need to not look like weapons.

The MT-2's limitation is that it requires direct physical contact — the user must be within arm's reach of the attacker and must press the electrodes against skin or thin clothing. This means the user is already in danger when the device becomes useful, which critics argue makes it a reactionary tool rather than a preventive one. VoltLine's response is that most street attacks begin at close range, and having any deterrent at contact distance is better than having none.
