LA Noire, Case 13 - "Quarter Moon Murders"
Start the case by examining the three objects on the desk, then go out into the garden and go up to the fountain (climb, literally) to collect and examine two other objects at the foot of the statue in the center: read the letter to the end, and examine the note to find out your next destination.
Once you reach the new location, talk to the man at the entrance, who will tell you to go up the stairs. At the top turn right and take the second corridor on your left, then turn left again and enter the room. After watching the movie, exit the room and get ready to do the balancing act: you will have to walk on the cables that support the large chandelier, to get on it and collect and examine the letter and the clock. An action scene similar to previous episodes will follow, then head to your next destination (the library).
Once you get close to the palace, you'll need to use the pipe on the outer wall to start climbing. Then use all the support points and holds you will find to go higher and higher, up to the top of the building, where to the left of the blue structure you will find two other objects to examine: a miniature and another letter. At this point you will have to examine the clues in your notebook to understand where to go to continue the investigation: you simply have to go west towards Westlake Tar Pits (set the destination on the map).
Once you reach the lake you will have to cross it: move the camera upwards to check where you will put your feet, and follow the walkway to the other shore. Here you will find two more items to examine: a women's shoe and a letter. Again, from the clues in your hands you should understand that the next destination is the art museum. This time you will have to wander around the hedge maze until you reach the center, where you will find two other objects: a ring and yet another letter. Your next destination is Intolerance Set, to the right and slightly lower on the map than your current location.
Once you reach your destination, go through the gate and go up the stairs, getting ready for a game of balance: you will have to balance your weight on the platform so as not to fall and reach the balcony in front of you unscathed. Take the first ladder on the left and go down: on the throne you will find the usual two objects (a coin and another letter). Examine them as usual and get ready to quickly escape the location as the floor literally collapses under your feet.
Your next destination is the Christ Crown of Thorns Church, slightly below your current location on the map. Watch the cutscene, then head right and go through the door and kick it open. Light yourself in the new room, continue through the kitchen and kick the door in the corner to open it. Watch a cutscene again, then examine the following items: the bloody tube on the floor, the surgery tools and the figurine on the table to the right.
Now you can go down into the catacombs, where you have to follow the suspect being careful not to get shot: use the system of cover and shoot at the right moment to hit him and complete the case.
