Meat Cannon

The meat cannon is a unique incendiary mortar and one of three secret weapons in Fallout: Brotherhood of Steel.

Gameplay
It's one of the most powerful weapons in the game, and can be obtained very soon if you know where to look.

Beware, if you equip it, you cannot dodge.

Pre-loaded explosive
With a few modifications, this weapon uses pre-loaded explosives bathed in blood and so it needs no ammunition. It shoots five explosives at the same time and causes considerable damage to anyone standing near the impact point, even the player.

Location

 * Los Bridge East, found in footlocker on hidden island.
