AM-27 Flechette

The AM-27 Flechette is a weapon found in System Shock.

Overview
Favored among TriOptimum security officers in the 2070's, this 6mm sub-machine gun fires needle-like ammunition.

While the increased magazine size and automatic fire are welcome upgrades from the Dart Pistol, the damage output is actually less until you get your hands on Splinter rounds. Thankfully the AM-27 has significant armor-piercing capability which offsets the decreased damage when facing robotic threats. It is also an effective weapon against mutants as many of them take double damage from needles and automatic fire makes deflecting their projectiles easy.

Trivia

 * Most of the weapons' names in System Shock are derived from the initials of the game's makers. In this case, AM stands for Alvaro Moreno.
