|The following is based on Fallout 3 cut content and has not been confirmed by canon sources.|
The inventory image and world model are the same as that of a standard frag grenade. It is set to only be usable by the player. It deals almost no damage and has no script assigned to it. After it is thrown, it simply disappears. Mid-flight, however, the red "danger" HUD icon for a grenade will appear on-screen.
This item cannot be found anywhere in the game and must be obtained using console commands.
