The StA4 is available only for the support class in Shadow Fall's multiplayer. In multiplayer, the Dot Laser is unlocked as standard, serving as the default weapon sight. However, as with most other weapons in multiplayer, the Holo sight and ACOG attachments are unlockable to increase scope magnification. The underbarrel Mobile Mine and Missile attachments are also unlockable.
The StA4 is fed from the right-hand side by a large, 75-round snail-drum magazine and has an average, 500rpm rate of fire. Its reload time, however, is significantly slower than most other automatic weapons in multiplayer, taking 5.5 seconds to complete.
The accuracy of hip fire is rather low, and the weapon suffers from significant and ungainly vertical recoil, as well as a large muzzle-flash.
