Taser is originally a brand name for a conducted electrical weapon that fires two barbed probes on wires, delivering a shock that locks up the target's muscles without a bullet. Police forces worldwide carry a version of it as a less lethal option next to a firearm. The name appeared in the September 2022 GTA 6 leak, read as a non-lethal option for dropping a target without killing them. Leaked material does not carry official confirmation, so Rockstar has not shown the range, the recovery time, or how targets react to being hit by one. A non-lethal option would fit the series' history of offering more than one way through a fight, but that is a reasonable guess rather than a confirmed detail. It stands as a leak until Rockstar says more.
