Killzone Wiki
"A solid performer in close to mid-range encounters, this gun features moderate fire rate, recoil, mag size, and damage output."
— Description

The StA-11 Submachine Gun is a Helghast Submachine Gun that debuted in Killzone 2.


Killzone 2[]

It has a cylindrical magazine that holds 48 rounds of the 9.2 x 20 mm cartridge, with a max-carry limit of 384, or 8 magazines. It has a high rate of fire and low recoil, which compensates for the low damage. Only downside is that the player must reload often in order to avoid being caught with an empty mag.

Firing from the hip is very effective at short range, though shouldering the weapon makes it dangerous at medium range as well. Interestingly, shouldering the weapon does not slow the player's movement speed as it does with all other weapons, although it does limit turnspeed slightly.

Killzone 3[]

"No other automatic weapon is better suited to close-range, in-your-face encounters than the StA11."
—Weapon description[src]

In Killzone 3, the StA-11 SMG appears largely unaltered, although its stopping power has been slightly increased. In the single player campaign, the SMG deals twice as much damage as an assault rifle at point blank range, and an equal amount of damage as an assault rifle at normal range. Killzone 3 also features the StA-11SE Submachine Gun, the suppressed version of the gun, in botzone.



  • The StA-11 SMG closely resembles both the real-world Russian made PP-19 Bizon, including the latter's high-capacity helical magazine, and the IMI Uzi, including the front sight and the open-bolt design. The rear iron sight group resembles a downsized version of the Belgian FN M249's.
  • It seems to eject two shells whenever it is fired, even when you fire just a single shot.
  • It fires the 9.2 x 20 round fired by the StA-18 pistol. This is similar to real world submachine guns that fire 9mm parabellum rounds fired by most pistols.
  • The 9.2 x 20 round appears to be a combination of the bullet diameter of the 9 x 18mm Makarov (which is 9.2mm), and the case length of the 9mm Browning Long (being 20mm length).
