ZombieMod takes a unique approach on the Zombie Apocalypse by putting it in the perspective of a military commander, not a survivor. Since it is 2 years after the first infections, resistance on the east coast is organized, resulting in battles rather than small groups fighting for survival.
A scratch-built flamethrower made from parts lying around, the "flame rifle" is a good boost to the builder's combat capabilities, allowing them to defend themselves. However, the fuel container has to be reloaded every once in a while, which can create a dangerous situation.
This is still a work in progress, and I am currently in the process of deciding whether it should have a backpack for the compressed air, or if the canister should be in the stock.
