In Extra Modes, It is Hunk's and Ghost's main weapon. The damage and accuracy are higher than default MQ 11 but LE 5 isn't effective to B.O.Ws such as lickers because of weak damage. LE 5 takes up 2 inventory cells, which makes item farming uncomfortable especially Ghost; he has only 8 inventory cells.
In Story, when you achieve S rank on hardcore if you choose any character or story, you can use infinite ammo version from item box.
