The Amped Kraber fires explosive rounds, very similar to unmodified 40mm Cannon in terms of damage and area of effect. One near hit will kill grunt, two consecutive near hits will kill pilot or Spectre.
The Amped version of the Kraber deals 8 times more damage to titans (800 damage), which makes this rifle devastating when used against Titan critical points. However, damage remains low against armor and miserable against titan shields. Also, when rodeoing an enemy Titan, using the Amped Kraber will cause suicide due to its splash damage.
