DUST 514 battlefield in the form of the Caldari rail rifle and the Minmitar combat rifle. These items join the Gallente assault rifle and Amarr scrambler rifle as the latest in DUST 514's race-specific weaponry; each gun possesses unique traits based on the preferences of the race that designed it.
The Minmitar combat rifle comes in three-shot burst and fully automatic variants. The Caldari rail rifle also comes in two variants; the assault version uses no sight and loses range for increased rate of fire, while the normal version fires slowly but with higher accuracy.
You can check out full crunchy breakdowns on both in the typical CCP style over on the official update post.
