The Abysswalker is a sensory-disruption killer that manipulates the FOV overlay and audio cues of the trial. The gameplay analysis covers the entity's power mechanics, the optimal perk synergies, and the best maps to play.
Power mechanics
The Abysswalker's primary power warps the survivor's FOV when the killer is within 20 studs, and distorts the audio of footsteps and Terror Radius. This creates an information asymmetry that the survivor must overcome to coordinate with their team.
The counter
Counters are Just A Scratch (no audio emission), a coordinated stack who never isolates, and Blessing: In The Shadows (Hidden status in 25/50/75 stud radius).
