The M7057/Defoliant Projector, more commonly known as the M7057 Flamethrower, is a UNSC heavy ground weapon used by certain members of the 5th Marine Expeditionary Unit. The M7057 is a donator weapon which has a price of $15.00 on the Altered donation page. Before use, Enlisted personnel must request permission of usage from an NCO, or Non-Commissioned Officer.
The M7057 behaves similar to it's portrayal in the various Halo games(and later Halo 5: Guardians) but was recreated for use in the Source Engine and thus has some restrictions due to a different engine. Players can also lower or raise their weapon by holding the reload button for a short moment (the R key by default). Unlike any other Halo-themed weapon in Garry's Mod, the flames of the thrower are capable of causing much more damage to an NPC or another player than any other weapon, and can hit targets through most environmental objects.
