The M12 Kobalt-F is a Nanite Systems anti-infantry primary weapon available to the Flash. The Kobalt is a fast firing machine gun able to deal damage to all lightly armored vehicles as well as infantry. It cannot, however, damage MBTs, Lightnings, Galaxies or Liberators. The M12 Kobalt's main purpose is to provide effective anti-infantry support to the Flash it is attached to, and with a high muzzle velocity, moderate fire rate and high damage, it does this job very well.
