This fully automatic weapon fires charged projectiles that break apart and create plasma on impact. Holding down the trigger causes it to steadily increase its rate of fire. Designed by geth, it is very effective against shields and synthetic targets. However, the significant mass of the weapon makes it difficult to carry, slowing movement speed.
With the Magazine Upgrade, the Spitfire can fire anywhere from 308 shots to 396 rounds before requiring a reload; and can exceed 473 rounds if combined with certain power evolutions.
With the Thermal Clip Storage, the Spitfire can hold anywhere from 660 shots to 780 shots before visiting an ammo dump; and can exceed 912 shots if combined with certain power evolutions.
The Spitfire has surprisingly good stability compared to the other machine gun type assault rifles. Stability mods/consumables may prove unnecessary.
The Spitfire will drastically reduce the movement speed of the player while equipped. Switching to a secondary weapon, or to one's missile launcher will speed the player back up.
The Geth Juggernaut is exempt from this penalty.
All Krogan aside from the Krogan Sentinel are also exempt.
For all other classes, using an Adrenaline Module III almost negates the speed penalty.
The Spitfire has an inherent 1.75 damage multiplier against Shields and Barriers.
When a geth multiplayer character uses this weapon, it inflicts more damage (only if points have been invested in the Networked AI passive power or Geth Juggernaut (power) for the Rank 6 bonus).
The Spitfire is extremely effective when equipped on a Geth Juggernaut Soldier. The Juggernaut's weapon damage and ammo capacity bonuses, bolstered by extra geth weapon damage and combined with its relative immunity to staggering, allows the Juggernaut to lay down immense amounts of devastating suppressive fire for extended periods of time. Combined with piercing mods or other damage modifiers such as gear or consumables, a Spitfire-equipped Juggernaut can easily take down armored targets.
