The StA409 continues with Helghast weapon design tradition, favouring volume of fire over accuracy with a high rate of fire. While the Keyzer features a smaller magazine than its previous incarnation, it is also vastly improved in terms of recoil and bullet spread. The new motorized drum magazine also allows for a faster reload, since the magazine lock will automatically move into place when the magazine is pushed in. Attachments are a new addition for Shadow Fall, allowing for optics and underbarrel attachments to be equipped. The StA409 can be equipped only by the Assault class in multiplayer.
