The official Arena Breakout international mobile site lists Misty Valley as a new Season 13 co-op extraction mode, mixing fog, urban legends and PvE teamwork into the familiar raid loop.

What the official Season 13 page highlights
This is more than a new backdrop. The official description says Misty Valley is a limited-time PvE extraction mode with no PvP combat, so squads can focus on routes, supplies and reacting to unknown enemies instead of watching every angle for another operator.
A different rhythm for squad play
That shift is what makes the mode interesting. It keeps the satisfaction of searching and extracting loot, while moving some pressure from gunfights to environmental decisions and cooperation. The site also mentions a limited-time double drop rate; exact availability and rewards still depend on the international mobile game client.
