Vertibot signal grenade

The Vertibot signal grenade is a weapon in Fallout 76.

Characteristics
Vertibot signal grenades are thrown just as any other grenade in the game, after it lands a plume of red smoke is seen rising from it. If the player doesn't have a friendly Vertibot, a prompt will appear on screen saying "No friendly vertibot can respond."

If they do, the vertibot signal grenade functions as a means to signal for a vertibot to land at the grenades location and pick up the person who deployed it, and transport them to a designated location.

Locations
Grafton steel yard - 10 can be found in a crate located on the vertibot landing pad.
