In Serious Sam 2, as of Update 2.90, the flamethrower can be made to appear in custom levels or added to the player's weapon inventory via cheats. In The Second Encounter the flamethrower is first found in Sierra de Chiapas, and then appears on the first level of every chapter onwards. However, the flame from the flamethrower has limited range, making it useful only for short range combat. The flame from the flamethrower can pierce multiple enemies.
In addition, any enemy that touches it will be set on fire, which will do extra damage to them. The fact that enemies will burn for a few moments after they've been hit makes this weapon even more effective. It is very effective for use on large masses, since the stream will engulf even partially hidden enemies. The flamethrower is an experimental weapon that uses highly volatile napalm fuel to deliver a jet stream of flesh-penetrating flame. 4.2 Serious Sam VR: The Second Encounter.4.1 Serious Sam HD: The Second Encounter.
