The map is set inside Wakaalu County Animal Shelter, where players have to rescue dogs that got kidnapped by a fictional org called Phoenix Biotechnical for illegal medical testing.
Gameplay wise, everything works exactly like the classic Hostage Rescue mode, except now instead of carrying a human hostage on your shoulder, you're literally carrying a dog.
Funny enough, this update dropped not long after a real life story about hundreds of beagles being rescued from a research facility in Wisconsin went viral worldwide.
On top of Shelter, this update also reworked the whole bomb explosion mechanic and brought the map Cache back into competitive rotation.
