The KRISS Vector (formerly the TDI Vector) uses an unconventional delayed blowback system to mitigate recoil that makes it useful for controlling automatic fire at close ranges. The KRISS Vector, with its low recoil and average damage is most useful in close to mid-range combat. Boasting high rate of fire and low recoil, this gun also has the benefit of having the most attachment slots of all the SMGs to further increase its performance. The major downside to this gun is — aside from it being less powerful than the UMP9 — its very small magazine capacity of just 13 rounds. Thus, extended magazines are a must for anyone wishing to use this gun further into the match.
