A flamethrower was used by Meredith Vickers to kill Charlie Holloway after he had been infected by Chemical A0-3959X.91 – 15. One was also later used by a mercenary in an attempt to kill the A0-3959X.91 – 15-infected Fifield in the Prometheus' hangar when Fifield began running rampant and killing crew members, but it proved ineffective against him. Another was used shortly later by Idris Janek to torch Fifield after he had been crushed by the wheels of an RT Series Group Transport.
