Riot prod

The Riot Prod is an electrically-charged prod that can knock a target unconscious. Used by security forces around the world, the Riot Prod is an effective tool for keeping what peace remains in the world.

The player will spawn with a Riot Prod.

Tactics
In a pacifist game, the Riot Prod is an extremely useful weapon. If aimed at the head and/or back, it can knock out MJ-12 troopers out with ease. Even the mighty MJ-12 Commandos can be downed if you hit them the belt on their backs. Getting good with this weapon is key to avoiding dangerous situations when you're sneaking around and have to get near enemies.

In a non-pacifist game, it's only useful for conserving ammo at the start of the game. Once you have a decent pile of ammo for your other weapons, dump it.
