Hugh telescope room: (Billy and Rebecca) (2)

Resident Evil 0 Hugh Telescope Room: Learn about the double doors leading to the balcony and the monkeys.

After returning up the ladder, you will find double doors that are locked. You can backtrack to the mansion to retrieve items if you wish. However, the double doors will no longer lead to the cage room; instead, they open to a balcony now occupied by numerous monkeys.
