UMP45 is a .45 submachine gun with a modest fire rate. The UMP45 fires slower than most SMGs, but its recoil is low and very predictable — which makes it reliable at mid range for its class.
Recoil character
The UMP45 fires slower than most SMGs, but its recoil is low and very predictable — which makes it reliable at mid range for its class. Vertical recoil is what you compensate; horizontal spread, timing and the decision to fire stay with you.
Setting it up in PUBG URC
Compensation is low: the calm fire rate builds the vertical gently. Compensation is calculated from your sensitivity, accounts for stance (standing, crouching, prone) and is set separately for each scope — it is not a fixed macro.
Scopes
The SMG class takes scopes up to 4x: red dot, 2x, 3x and 4x. Most of the work with UMP45 is on the red dot and 2x at close range, so tune those first.
Tip
One of the few SMGs comfortable on 3x — use that in transitional fights.
