This high-caliber marksman rifle trades magazine capacity and rate of fire for powerful, accurate shots.

— Armory Description

The R-63 Diligence is a marksman rifle that fires high damaging shots. Although it does not have as much damage as assault rifles, it makes up for it when the user takes the time to line up and hit weakspots on enemies. The Diligence kills most enemies in one to two shots in the head.


It is unlocked on the 2nd page of the Helldivers Mobilize Warbond for 8 Medals.
