Non-Lethal Trap?????

Hey guys! Fellow survivor here with a question. I've been playing NS for a while now and I have been thoroughly enjoying it so far and I even managed to kill the Merga Wraith and acquire both legendary reputations.
However, when I was browsing around in the fandom wiki, I came across another combat move I have yet to see called the "Non-Lethal trap" given by the Unstoppable reputation. I was wondering why I can't find more information on this move and if it is actually in the game or not. It is kinda bugging me..anyway thanks for reading!
