Sometimes when playing as the Hunter (Mei) in Mei's Yeti Hunt, I'll briefly see the Yeti (Winston) through walls as a red spot. This is the same effect from Widowmaker's Infra-Sight or Hanzo's Scatter Arrow.
Why can I sometimes see the Yeti through walls as the Hunter?
Best Answer
Anytime your teammate hits the Yeti you can see his location for a short time, even through walls.
This is shown on the Hero Ability menu as the passive Teamwork ability.
