The Wolf Medal, like the Eagle Medal, is an item used in puzzles in several Umbrella facilities.
Found in Doom book 2 and used in conjuction with the Eagle Medal to gain access to the fountain elevator leading to the laboratory underneath the mansion.
Resident Evil 2Edit
The Wolf Medal is found in a small alcove by searching a dead Umbrella mercenaries corpse, directly in front of the fan that you have to climb into. It is one of two medals needed to stop the flow of the water in the sewers, the second of which is the Eagle Medal.
