The perk description says: "Grants a 5% Haste Status Effect for X seconds after damaging a generator, or breaking a breakable wall or pallet [while chasing the Obsession]."
A few Killers have their own ways of breaking generators, walls or pallets, such as (but not limited to): any chainsaw Killer, Nemesis (Mutation level of 2+), Knight. Additionally any Killer can have an "alternative" way of breaking pallets with the effect of the perk Spirit Fury.
Do these alternative ways of breaking objects trigger the Game Afoot effect?
For example, if I am in chase with the Obsession as the Knight, and I send a guard to break a pallet, do I get the Haste effect? If it does work, does it work with all alternative break actions of all Killers (including Spirit Fury) or are there exceptions?
