M-451 Firestorm

The M-451 Firestorm is heavy weapon from Mass Effect 2.

In-Game Description
Based on the turian "Hieras" flamethrower, the Firestorm is an anti-personnel and anti-armor flame unit that can accept a wide variety of liquid fuels. The turian design used low-octane hydrocarbons thickened with dentra oil, which is taken from large marine animals similar to Earth's whales. Humans then reverse-engineered a synthetic composite with almost identical properties that could be fabricated from heavy weapon fuel cells using an omni-tool. The result is a sticky spray that burns at approximately 1,600 degrees Celsius, a less intense fire than plasma weapons but covering a significantly wider target area.

Acquisition
The M-451 Firestorm can be found during Zaeed Massani's loyalty quest, on the body of a dead mercenary. Zaeed and his quest are available as a downloadable content pack for Mass Effect 2.

Player Notes

 * It is similar to the Collector Particle Beam or the enemy Pyro flamethrowers, firing a burst of flame straight ahead. This is a short-range weapon.
 * The Firestorm is an excellent option for 'crowd control'. This weapon is extremely effective against swarming, melee-based units such as husks and varren. The weapon's armor damage modifier is also helpful at higher campaign levels (ie. Veteran, Insanity), where many melee units possess armor.
 * The Firestorm is an excellent weapon for classes without shotgun training since it provides a very potent short range weapon as well as for Soldiers using the Vindicator asault rifle since it's constant stream of fire helps compensate for the player's lack of a true fully automatic weapon.
 * The Firestorm uses power cells much more efficiently than any other heavy weapon and can thus be used far more frequently.

Trivia

 * The name of this weapon references the book Fahrenheit 451 by Ray Bradbury.
