ARC Machines
Weak points, XP and the drops worth knowing.
Three new ARC
- Bully: aggressive and fast. It gallops straight at you and doesn't give ground. Use cover and time your answer.
- Skulker: opportunistic. It waits at the edge of your vision and ambushes you when you look away.
- Hydra: a three-part stacked turret found on the Frigate, able to hold off a whole squad. Split its attention, find cover fast, and strike when it's busy.
- Already live since 1.45.0: Snitch Scanners call in ARC like regular Snitches (with a lower chance of the stronger ones), and the Matriarch's stomp no longer hits through tall cover.
