"A liquid insulating agent is constantly circulated through the floor of the experimentation chamber located in the middle of Umbrella's R&D Center. The capsules have a capacity of over 200 liters and a specially built ultra-powerful frame keeps the room safely contained."
The Nursery is an area of the Umbrella R&D Center in Raccoon City. It appears in the "end of the road" scenario of Resident Evil Outbreak File 2. In the Japanese version of the game it is known as the incubation room (培養室 baiyō-shitsu )
This room is used for the gestation of bio-weapons, sealed inside four capsules on one side of the room.
When exploring this room, the completed Hunter Mu will break out of their capsules.
