The AR-2 Coyote unlocks at level 35 and appears as the Kalashnikov Concern AK-12 (AK17 Rifle).
Released in Helldivers 2's Dust Devils Warbond, this weapon functions pretty much like its Helldivers 2 counterpart: The rifle is loaded with high potency incendiary rounds which set anything they hit ablaze, whilst having pretty average accuracy and recoil control. The drawback to having high damage and fiery bullets, this weapon will not benefit from damage boosters whatsoever, be it from a perk deck or any crit skills.
Since the Coyote doesn't come with an optic by default, it has a selection of some Helldivers 2 optics available.
