"Speed and lethality."
The Blitzen weapon platform starts off with the L-ADV and the S-ADV, or Long Advanced and Short Advanced.

The Blitzen platform firearms are both rifle-caliber weapons for both medium and close range combat. Their unique internal design massively reduces recoil without sacrificing rate of fire.

The L-ADV fires at a very respectable 800 rounds per minute and boasts superior accuracy, while the compact S-ADV fires at a blistering 1000 rounds per minute. As expected, the intense rate of fire of the S-ADV does hamper ranged performance.
