"Delivering a continuous stream of burning liquid, the Flamer can set large crowds of infected on fire. Fire spreads easily, so extreme caution is advised!" -Dead Nation description
This is a pretty straightforward weapon, It delivers a stream of fire that can cripple hordes of infected. The Flamethrower isn't much of a primary weapon, instead i behaves more like an aimable Molotov. As the description says, the player should be careful while using this weapon, as they can also be set ablaze while using this weapon if a burning infected makes contact with them though this can be avoided by dashing.
