The KRISS Vector, known as Vector in-game, is an SMG with both 9mm and .45 ACP variants. The 9mm variant was added in the v0.3.6 "Three heads are better than one" update on May 10, 2018, while the .45 ACP variant was added in the v0.6.5 "Gunfight at the Deadeye Saloon" event update on November 9, 2018.

Update Note

"The Vector submachine gun: it's time to put those 420 rounds of 9mm sitting in your backpack to use. Spitting 33 bullets at a rate of fire even the MAC-10 would be envious of, this modern piece of weapons technology will chew through ammo faster than you can say "reload." Grab this gun, and you'll be pointed straight towards a chicken dinner."


The Vector can often be found in the inner-most room of the Hydra Bunker or inside of a Storm Bunker, inside Hatchet Cases. It is very rarely found as a drop from Crates and Containers, or as ground loot. It is also common in Meteor Crates.

The Vector uses 9mm (yellow) Ammunition and spawns with two rounds of 99 total 9mm (about 49.5x each). It has a magazine size of 33 bullets, a reload time of 1.6 seconds, and a 0.038-second delay between shots. It is extremely accurate and fires extremely fast, though with a limited range about the length of a 4x Scope screen. The .45 ACP version is identical but does slightly more damage than its 9mm counterpart for an expense of reduced ammo capacity of 25 and a 6-millisecond extra delay. The .45 ACP variant also has higher DPS.



  • The Vector is a versatile SMG that is well paired with most guns.
  • This gun can be used to flush Container campers out due to the good accuracy and high fire rate.
  • It can also be used by bush campers to ambush close targets due to the good accuracy and high fire rate.
  • When using a Vector, use your Ammunition sparingly. With its fast fire rate, it burns ammo like Dual G18Cs. When it is near/end-game, it is best to fire in the open. Try to lure out with your enemies with Frag Grenades.
  • Try to burst fire when your enemies are on the move, which might increase your chance of hits. It also conserves your ammo as compared to fully automatic.
  • The Vector is exceedingly useful in close quarters because of how it fires around the speed of Dual G18Cs or a MAC-10 (Although both weapons outclass the Vector at close range in terms of DPS, the Vector's accuracy and reload time make it a better choice anywhere beyond point blank. It is virtually impossible to dodge the bullets if the user can aim well, and spread is surprisingly good considering how powerful a spray gun is.
    • However, be careful in close range where the walls deflect bullets, like in Bunkers, as you might accidentally kill yourself. Try to avoid using the Vector in bunkers unless you have armor.
  • The Vector serves as a good replacement to Shotguns and can be paired with a long-distance or other high-damage guns.
  • If you have the Endless Ammo Perk, you won't have to worry about conserving ammo. You can relentlessly charge at enemy cover positions. Mind the fact that you still have to reload.
  • Contrary to many people who advise fire discipline, this weapon has an insanely fast reload time to go with its fast fire rate; the only actions in the game faster than a Vectors reload is the single P30L (not dual), and the one-at-a-time reloads of the M870, SPAS-12, M1100, Model 94, and Mosin-Nagant. Anytime you stop firing for whatever reason, reload. Also, to contradict the ammo burn, the Vector will usually quickly reward many kills that will help refill this weapon's ammo pool, as 9mm and .45 ACP are both extremely commonplace, and pretty much everyone is carrying some of it when you reach the final top 5 of a round. However, do avoid using this weapon at anything longer than mid-range.
  • At close range, be sure that you can aim, as the Vector is quite accurate at close range, and a shotgun user may dodge the bullets and kill you.
  • This surprisingly is amazing when paired with a BAR M1918 or any other LMG because you can take out hiding spots while advancing and then finish them with the Vector.
  • The Vector is even more powerful when paired with perks such as Splinter Rounds or Explosive Rounds, as they increase the Vector's damage per shot (considering all three splintered bullets hit an opponent, dealing 115% of the normal damage of the Vector), as well as its DPS.


  • Unless you are good at dodging and have good armor, full health, and adrenaline, don't go in front of the Vector. It means instant death since the gun is so accurate. Practically all the bullets will hit you because of the gun's insane fire rate and decent spread/accuracy at medium and close range.
  • Don't underestimate the low damage per bullet, as the fire rate and accuracy more than makes up for it.
  • The Vector has a longer range than most Shotguns and is effective in close to mid-range. However, it is not effective enough to hit you with long-range. The main counter for the Vector is to move around and keep your range. The Vector fires so fast that if you move around, all the bullets will spread, and almost none or few of the bullets will hit you
  • The Vector has an extremely short reload time, which means that it uses 9mm ammo fast. You can deliberately make your enemy repeatedly use their 9mm Ammunition so they can run out of it. When they finally run out of Ammunition, attack them. Be careful, though, as they might have an already loaded secondary weapon.
  • The Vector is best countered by the SPAS-12 or Sniper Rifles like the SV-98 due to them having a longer range and accuracy compared to the Vector.
  • You can also use high-damaging assault rifles like the SCAR-H and the M4A1-S because they deal more damage and have a longer range than the Vector.
  • Using Shotguns other than the SPAS-12 or Super 90 isn't the best option for going against a Vector due to its higher range and damage.
  • If you are a camper or have good equipment, you can rush the Vector user with a shotgun, preferably the MP220 or Saiga-12.
  • Be aware that if you see this weapon on the ground somewhere, the odds are good that someone is using it to bait people into a trap because of it's rarity, usefulness, and popularity. Look around for areas other survivrs can hide before you rush towards it. This is less true in the Desert Map, though, because it's not as rare.

The Vector is a rare SMG that spawns mainly in Hatchet Cases in the Hydra Bunker and rarely in the Storm Bunker (10% chance). It also drops in Air Drops, rarely as Tier Chest loot, or very rarely spawn as Tier World loot. The .45 ACP variant can be found in the basement of the Saloon, in Hardstone Boulders, and in Air Drops in the Desert Map.

  • In the game, Vector's fire rate is phenomenally high, firing over 1500 rounds per minute. While the Vector prototype version had a fire rate of 1500 RPM, the current production model only has a fire rate of 1200. This could mean the Vector in-game could be a production model modified to fire as fast as the prototype.
  • The Vector has an unconventional delayed blowback system combined with an in-line design to reduce perceived recoil and muzzle climb, which could explain why it's so accurate.
  • The 9mm Vector's sprite is correctly drawn with a 33-round 9mm Glock extended magazine, while the .45 ACP version uses the original 25-round .45 ACP magazine.
  • The 9mm Vector icon shows it with a custom Magpul MOE SL Carbine Stock in place of the actual Vector's stock. Adapters exist in real-life that let the Vector take stocks such as this one. The .45 version uses the original stock for the Vector and has a new foregrip drawn on the front.
    • The stock on the 9mm Vector is used on the M4 and other variants of the Mk 18 CQBR.
  • It's the first gun to have an alternate variant, as well as a variant that uses a different ammo type. The standard version uses 9mm while the desert variant uses .45 ACP.
  • The KRISS Vector is a submachine gun designed in 2006 and produced in 2009 by KRISS USA Inc.
    • The Vector is used in Indonesia, Thailand, the Philippines, and the United States, but other than those countries, law enforcement and military usage of this weapon are limited.
