The KRISS Vector for DayZ: a .45 ACP submachine gun with a very high rate of fire and low recoil. It has its own magazines, two suppressors, a rail guard, a stock and a grip, all in eight colours.

  • Very fast full auto. About 1,800 rounds a minute, three times the UMP-45.
  • Low recoil. A quarter less than the UMP-45 bare. Fully kitted, it kicks about a quarter as much.
  • Faster bullets than the UMP-45, with tighter grouping.
  • Its own magazines: a 13-round standard mag and a 33-round extended mag. Both load with vanilla .45 ACP rounds.
  • Five attachment slots: optic, muzzle (two suppressors to choose from), rail guard, stock and grip.
  • Eight colours: black, yellow, grey, white, cyan, camo black, camo brown and camo purple.

Colours

Every item except the 13-round magazine comes in eight colours. The colour is in brackets after the name:

Colour Name in game
Black No suffix, for example Vector
Yellow (Yellow)
Grey (Grey)
White (White)
Cyan (Cyan)
Camo Black (CB)
Camo Brown (CBr)
Camo Purple (CP)

Colours are cosmetic. Any colour of attachment or magazine fits any colour of Vector.

Getting started

  1. Load .45 ACP rounds into a Vector magazine, the same way as any vanilla magazine.
  2. Attach the magazine to the Vector.
  3. Add attachments as you find them.

You can also chamber a single loose .45 ACP round directly, like any vanilla rifle.

The Vector only takes Vector magazines. UMP-45 magazines don't fit.

Attachments

Slot Takes
Optic Any vanilla rifle optic that fits the M4: ACOG, M68, reflex, holographic, T3N, BUIS, carry handle
Muzzle Vector Suppressor or Vector Suppressor 2
Rail guard Vector Rail Guard
Stock Vector Stock
Grip Vector Grip

Vanilla suppressors, bayonets and flashlights don't fit.

What each attachment does

Attachment Recoil Sway Other
Vector Suppressor 25% less 10% more Suppresses the shot, slightly tighter grouping
Vector Suppressor 2 30% less 30% more Quieter than the Suppressor, slightly tighter grouping
Vector Rail Guard 20% less 30% less
Vector Stock 30% less 30% less
Vector Grip 25% less 25% less Slightly tighter grouping

The effects stack. A Vector with a stock, grip, rail guard and either suppressor has about a quarter of the recoil of a bare UMP-45.

One suppressor at a time. The two suppressors use separate slots, but a Vector with one fitted won't take the other. Take the first one off to swap.

Handling

Vector UMP-45 (vanilla)
Fire modes Semi-auto, full auto Semi-auto, full auto
Rate of fire, full auto about 1,800 rounds a minute about 610 rounds a minute
Muzzle velocity about 325 m/s about 275 m/s
Recoil, bare 75% 100%
Weapon health 500 250
  • A 33-round magazine empties in just over a second on full auto. Fire in short bursts.
  • The Vector uses the UMP-45's sounds, reload and handling animations.

Troubleshooting

Problem What to do
A UMP-45 magazine won't attach The Vector only takes Vector magazines
A suppressor won't attach The other Vector suppressor is already fitted. Remove it first
A vanilla suppressor won't attach Only the two Vector suppressors fit
An optic won't attach It needs to be a rifle optic that fits the M4. Hunting scopes, PSO scopes and pistol optics don't fit
