Flamethrower

For the Flamethrower in Deus Ex: Invisible War, see Flamethrower (DX2).

Background
A Flamethrower fires burning napalm at enemies.

Tactics
The Flamethrower is a powerful weapon as it intantly sets enemies on fire. Enemies on fire continuously take damage and run around helplessly. A single ignite on Untrained is enough to kill just about anything in the game except for very HP heavy enemies like Men in Black who require either two ignites or Advanced Heavy Weapons skill.

Unfortunately, while the flamethrower is very effective against some enemies, it's next to useless against others. It does next to no damage to robots and half damage to Commandos. Furthermore, Commandos cannot be set on fire, which means you would need one full canister of fuel and Advanced heavy weapons skill to kill just one Commando.

It can be found very early in the game hovewer - one of the NSF soldiers in tunnels under Castle Clinton wields it - and until Commandos start to appear it will be extremely effective.

In-game description
A portable flamethrower that discards the old and highly dangerous backpack fuel delivery system in favor of pressurized canisters of napalm. Inexperienced agents will find that a flamethrower can be difficult to maneuver, however.
