The Perdition was the standard issue weapon of Koprulu Sectorfirebats by 2480. The combusto-plasma fuel is stored in containment fields but pose an explosive hazard if the fields are breached violently. The plasma fuel easily seeps between gaps in zerg armor; smaller strains are literally cooked alive in their own skin.
Marines and firebats are careful about utilizing perdition flamethrowers, and only do so when all squad members in the firing radius has fully functioning CMC Powered Combat Suits, as the backfire can lead to catching allies on fire.
