"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.
