I was thinking of something like that too. Not hide and seek but a Survival.
One hero vs 4 Monsters hunting you down through the Chateau.
Similar to Yeti Hunter where the single player is buffed with speed and such for survival. And the monster instead of ults have maybe a stun, you know like a shock that falters the one just enough slow them down.
And the single player getting something like some kind of burst/boost for them.
Single player either needing to get a kill on all four to win. The Monsters needing to take down the Single player to win. Time up would end in a draw.
