The M7057/Defoliant Projector, more commonly known as the M7057 flamethrower, is an incendiary weapon used primarily against battlefield fortifications, protected emplacements and installations, and for demoralization purposes. It is a variation of the NA4/Defoliant Projector.
The M7057 flamethrower is a standard chemical flamethrower, which projects and ignites a stream of a volatile, semi-liquid adhesive known as Pyrosene-V. Like the M6634, the M7057 flamethrower is cumbersome and relatively difficult to tactically use (psychologically as well as mechanically). In its role as a defoliant projector, it is designed to be used to rapidly clear away heavy foliage for in-theater construction projects and to destroy new or persistent growth from emplaced and/or hardened military assets. Despite being all but obsolete militarily its effectiveness as a psychological weapon is undeniable—unfortunately, the psychological effect is a double-edged sword. The psychological impact of employing an M7057 makes it one in a very small number of items available to UNSC personnel that remotely earmarks the user for a full battery of psychological tests. Due to the weapon's massive size and weight, it is usually deployed with a cart on which to transport it. Despite this, however, UNSC Hellbringers have been known to employ the M7057 seemingly unassisted and without issue. In 2553, Hala was able to use an M7057 unassisted to torch a Sahara-class heavy prowler. During the Second Ark Conflict, two M7057s were fitted onto a specialised Cyclops employed by Lt. Colonel Morgan Kinsano as heavy weapons.
The weapon was one of many featured in Machines, Materiel and Munitions from the Human-Covenant Conflict, 2525 - Present.
- M705 Incendiary Jet Tool: Nicknamed the I-JeT, the M705 is a compact, vacuum-suitable variant of the M7057 fed by a tank-pack full of self-oxidizing fuel.
- Cryosprayer: Instead of fire, this weapon shoots ice at the enemy, causing them to be slowly frozen.
The flamethrower makes its first gameplay appearance in Halo: Combat Evolved for PC's multiplayer, later in Halo 3 and Halo 3: ODST, as well as Halo: The Master Chief Collection. The weapon's range is similar to the shotgun, which is only effective at close-quarters. When fired within range, the flamethrower deals lethal damage to unshielded opponents. Against shielded opponents, it will remove their shields and apply a substantial amount of damage to the opponent's health. The flamethrower overheats if used continuously.
The flamethrower functions differently in both Halo PC and Halo 3/Halo 3: ODST. In Halo 3, the flamethrower is one of the few support weapons. Players wielding the weapon would move at a slower pace and from a third-person perspective. Moreover, they would not be able to melee or use any of their grenades or equipment. The flamethrower is no longer useful once the fuel has been depleted. In comparison, the Halo PC version does not hinder the player's movement, allows the weapon to be reloaded with new fuel canisters and does not prevent meleeing. However, the damage dealt is weaker compared to the version used in Halo 3. In Halo: The Master Chief Collection, the flamethrower functions identical to the Halo PC flamethrower. In Halo 3, it is one of two human weapons that overheat, with the other being the M6 Spartan Laser. It has a built-in fail-safe system that stops the weapon firing when it reaches a certain temperature. If the weapon could be fired while overheated, it would melt or explode, and the heat and the flames would harm the user.
With the flamethrower's campaign introduction in Halo 3, it has become one of the best anti-Flood weapons. The hardest type of Flood to fight, the Flood pure forms, will die nearly instantly, upon lighting on fire, and destroy any Pod infectors that run over the flames. Though still highly effective against Flood combat forms, they still live for some time while on fire, which can produce some awkward combat moments of avoiding their charging, flaming bodies. Given light of this, it is not recommended using the Flamethrower in cramped spaces, many of which can be found in the levels Floodgate or Cortana, as the flaming Flood will lead to frustrating suicides.
A good attribute is that it can begin killing multiple Combat Forms at once, thereby being as functionally effective as the gravity hammer, with the ones on fire possibly lighting other ones on fire. Once they die, their bodies are consumed by the fire and will not be able to be resurrected by Pod infectors. In fact, any Pod infector that runs towards the body will also be destroyed by the flame. It can also be used to destroy a pile of Combat Forms, so they won't come back if a Pod infector finds them.
It is also very handy to handle Flood carrier forms, as lighting it on fire can cause the Pod Infector not to disperse upon death. One precision bullet was sufficient to kill Flood Pure Forms, and it also affects all Flood Forms.
Note that if the player stands around the flames emitted by Flamethrower, it will receive an effect akin to Brutes or players using Flare. It also effects when the Flood on fire is around the player.
The Flamethrower can also be used to form a “defensive perimeter” by burning the ground or any solid objects surrounding it, which can be very useful at level Cortana at cramped spaces to give a player a room to breathe for a set of time. Any flood forms stepping on it will be immediately on fire, but it can also harm the player if a player chooses to traverse over the flame before it dissipates.
In Halo 3: ODST, Flamethrower can be your ace in the hole weapon. It can easily pierce Jackals Kig-Yar point defense gauntlet while for Jiralhanae power armor, it can break its armor while sometimes can score a direct kill immediately in one direct hit. If not, the Brutes are often going slightly panicked when on fire.
Although it can be only found at Data Hive, it can help your progress much easier except for dealing with the hordes of Yanme'e when going through their nest. However, the player needs to be careful since lighting Vergil on fire directly at any difficulty can result in immediately killing it.
The flamethrower is a support weapon, and a support weapon only. If you are wielding this weapon, you back up your teammates. Lighting a whole team on fire can help out your teammates, by weakening their shields. Just be careful, if used incorrectly, you could set your whole team on fire, the flame spreads easily.
The flamethrower is best used in close quarters combat. The trail of flame can act as a temporary smokescreen to blind snipers with. It's especially effective if used to retreat by running backwards away from an enemy to leave a trail of flame, deterring would-be pursuers from giving chase to a wall of fire, use caution because the flamethrower's damage is reduced when running backwards. It is effective as a denial or area weapon, you can set fire to doorways or flags to discourage anyone from crossing that area, and damaging those that do (possibly even catching on fire and killing unshielded opponents).
As a Slayer weapon, it is recommended to use it to surprise people entering enclosed spaces, as it is very lethal up close. You can shoot the flames around a corner as you run backwards around a corner, and any opponents who choose to take the risk of pursuing them will be roasted by flames but unable to get a line of sight to get you themselves.
Sometimes, players even wait near some strategic points, with active camouflage and a flamethrower, for example they may wait at the point at which players land after flying out of a man cannon and burn the helpless victims. Or sometimes they can hide at one side of a door and when a player runs out, they can burn the unsuspecting player to ashes.
Most types of equipment can often be used to your advantage when escaping the flames, like deploying a radar jammer (although it is now not available in matchmaking) to confuse the enemy if they can't exactly see you due to the continuous flames, and since you'll be moving about, the enemy can't exactly identify you from the “fake” red dots on his/her radar. Deploying a power drain will cause the wielder of the Flamethrower to cease fire temporary to avoid having their shields to be drained if smart enough, however, if the wielder continues to fire they risk being drained of shields and made an easy target to any enemy players in the vicinity.

- The Defoliant Projector was inspired by a similar flamethrower from the Marathon series. The Defoliant Projector's number, 7057, is an alpha-numeric call-back to the weapon from Marathon's name, the TOZT which means toast in leetspeak.
- The shark-like decal on its heat shroud is borrowed from the American Curtiss P-40 Warhawk made famous by the Flying Tigers (American Volunteer Group) during the Second World War. Aircraft of the 23rd Fighter Group, the Flying Tiger's modern-day successor, continue the use of the shark teeth decoration.
- The Dragon's Breath rocket launcher from Bungie's Destiny series uses a similar muzzle aesthetic as well as the real-world XM42 flamethrower Gen 3.
- In the cutscene of the Halo: Combat Evolved level Keyes, where the Master Chief retrieves Captain Jacob Keyes' neural implants, the Master Chief was meant to burn Keyes' skull out of the Proto-Gravemind and retrieve the implants. Unfortunately, due to time constraints, the Flamethrower was removed. Lorraine McLees was the one who actually had to texture the whole "burnt" skull and she added that she had done her job so well that "the skull was so gruesome no one could look at it."
- The Flamethrower ultimately made its in-game debut in Halo: Combat Evolved for PC. The weapon was later considered for inclusion in Halo 2, and one of several similarly-cut weapons. It was finally realised in Halo 3.
- In the 1999 E3 trailer, the flamethrower looked drastically different. The fuel tank stuck far out of the side, and the whole weapon seemed to be painted bright red.
- In Halo: Combat Evolved, when a Spartan wields a flamethrower, he flips back a cover to expose a button. Next to the button is the character 下 or 'xia' (meaning "down" in Chinese).
- In Halo: Combat Evolved, the flamethrower shares the same reticule with the M90 Shotgun and the Sniper Rifle System 99C-Series 2 Anti-Matériel. In Halo: The Master Chief Collection, the reticule for the flamethrower in Halo: Combat Evolved has been updated to match the reticule from Halo 3.
- In Halo Custom Edition, Flood combat forms are able to wield the flamethrower. The only way to observe this is to play start a "Heavy Slayer" game on a map that spawns Combat forms. The Combat form will hold it upwards, making the weapon useless in their hands since the fire will go upwards without hurting anyone in front of the form. The reason why the flamethrower is compatible with Combat forms is because the flamethrower was supposed to appear in the level Keyes, and Bungie programmed Combat forms to be able to carry it in order to grant the player easier accessibility. The player was then to use an acquired flamethrower to burn Captain Keys' skull from the Proto-Gravemind in order to retrieve his neural implants.
- Work was done on a flamethrower weapon for Halo 2 but it was not completed. The bonus materials featured in the Limited Collector's Edition feature renders and in-game footage of the weapon which has a different design than the Halo: CE and Halo 3 versions. This design was featured on the cover of Halo: The Graphic Novel.
- Strangely, even though UNSC Marines claim that their comrades wield the flamethrower, the player can not give it to them in game. This may be due to game balance issues. The only time when a Marine is seen wielding one ever is at the Halo 3 level Floodgate, it is seen being used inside the factory, (the spot where any surviving Marines hold position) holding it like Master Chief. One needs to be in Theater mode or playing on a lower difficulty to see the Marine holding it, because he dies in a few seconds.
- In Halo 3, the flamethrower still works underwater. However the flames must have already clumped to something and spraying into the water will have no effect. Strangely, in Avalanche and Snowbound, if one fires at the snow it will burn as if it is ground.
- In Halo 3, the flamethrower can be used to easily achieve a Death from the Grave Medal or an Incineration Medal. If the player simply hit an enemy with enough sustained fire, it will kill them. If the player has already hit an enemy with the flamethrower when they dies, they will die via flame damage seconds later.
- In Halo 3: ODST, the flamethrower and the Assault Rifle are the only weapons that appeared in campaign but not in Firefight.
- In Firefight, it's only exclusive for only one mode following April 2022 update, Floodfight. The Flamethrower would only appear on several maps as a Power Weapon to fight off Flood Forms at Floodfight.
- In Halo 3: ODST level Data Hive, players who kill 10 Covenant troops with the flamethrower are rewarded by the "I Like Fire" achievement.
- In Halo Wars 2, the flamethrower was modified by Serina to be suited for Cryo weaponry, and can be used by Cryo Troopers if the player picks Serina as Leader.
