In Fallout: Brotherhood of Steel, there are three secret weapons: the meat cannon, the Slugger and a special version of Red Ryder BB gun. They are roughly equivalent to the unique weapons in Fallout 3, at least in case of the meat cannon and the Slugger.
The meat cannon is a unique incendiary mortar.
The meat cannon is one of the most powerful weapons in the game, and can be obtained very soon in the game if one knows where to look. Beware, if equipped it, the player can not dodge. 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.
- Los Bridge East, Found in footlocker on hidden island.
To find this, the player must leap into the dark void just to the east of the last save game terminal near the level's exit. This will not result in death and the player must continue straight on towards of a destroyed bridge. A little farther from it, one must kill all the ghouls in the area and loot the footlocker toward the ice cream truck.
Red Ryder BB gunEdit
This special Red Ryder BB gun is a unique version of standard Red Ryder BB gun.
Thanks to his high knowledge in repair, the Vault Dweller has modified a Red Ryder BB Gun for it absorbs and propels the surrounding air, forming a ball of air, so it needs no ammunition. But since the air is hard to control, its damage is changing and may be very low or very powerful.
- Carbon Warehouse Main Storage, given by the Vault Dweller if all the survivors of the raider attack on Carbon are saved.
The Slugger is a unique spiked baseball bat.
It's a very powerful weapon for Chapter 2 and remains very good even in Chapter 3. It has powerful critical damage, and every critical hit knocks back enemies a good distance. Despite these characteristics, in Chapter 3, there are better melee weapons.
- Docks of Los, found on the secret giant glowing ghoul's corpse.
To obtain this weapon, when the player is on the Docks Shipyard, they must check all of the alleyways north of the large area of radioactivity until coming across a couple of glowing ghouls standing behind an unscalable fence. They cannot be reached by standard weapons, but they can be hit with explosives or another weapons like incendiary mortar. Once these ghouls are killed, a giant glowing ghoul will spawn just outside the alley's entrance. Then, after he has been killed, he will drop the Slugger.
