The Homemade Flamethrower is the lowest-tier flamethrower.
How to build:[]
The things you will require are (in order):
The Leafblower can be bought from the Hardware Store (requires Director's Cut) for $1900.
The 40oz. can be bought from 11-Seven for $90, or as loot from fighting the Eastside Mobster outside the Penthouse Suites.
The Lighter can be bought from Steel and Hawk or The Contraband Salesman for $75.
Bring the items to Pyro Perry, who will then give the player the Homemade Flamethrower and increased stats.
