The LS21 Valk is one of three submachine guns in Shadow Fall, and the first of two that are available to the Assault class in multiplayer. The Valk has a high rate of fire, but lacks stopping power and has a smaller magazine capacity. It is quite compact and a solid choice for players that prefer to rush around the map with an aggressive playstyle. The Valk has a unique, built-in burst fire feature. You can tap the fire button to fire a burst of three bullets, or hold the trigger down for fully automatic firing. The LS21 has 3 scopes and 2 underbarrels. The gun is sometimes equiped with a laser dot scope, a holo scope and a AGOG scope and for under barrels are a shotgun underbarrel and a laser underbarrel which increases its accurcy.
