The Krube-37 is the Tier 2 submachine gun to be unlocked. It features an above-average accuracy and rate of fire, but loses stopping power fast as the range increases. Compared to the Sabre-S2, the Krube-37 features a better fire rate, accuracy, slightly higher armor penetration, and is one of the few submachine guns which can equip grips to improve accuracy even further. While this gives it improved effectiveness at longer ranges compared to other SMGs, its low damage and noticeable damage drop-off still limit its effectiveness primarily to close-mid range combat. This weapon is modeled after the Kriss Vector, a firearm.
