In Resident Evil 4 Remake, while Leon is searching for Ashley, he finds he must first find the key to the church. Once he does, he is met with a puzzle blocking his way, two statues, and a mural of other locations in the lake that he must solve to get the key. When he looks at it, the map will be updated with two locations where Leon must unlock a door.
