Here is a character sheet for the Morrow Project (or rather “Project Phoenix”) that uses the White Wolf nWOD “Storyteller System”
The X-26 is almost within the canon dates (a form of Taser was manufactured in the 1970’s) . In any event, this is an optional addition to the Project’s “less-lethal” capabilities.
Rules: this deice is 95% effective. If a successful hit is achieved (Pistol skill) then the target should make a saving roll – only a roll of 95 to 100 will allow ANY action while the taser is active.
