This brief guide may include minor spoilers. There are six cardboard standees, which can be found in the following order:
Odin Anderson: You will be ambushed inside a store, and after fighting off the Taken you will emerge in a parking lot full of bright red lights. With your back against the door you exited from, head around the right side of the building to find this standee in a corner by the fence.
Sarah Breaker: After exiting the parking lot area mentioned above you can use the focus button to get a full view of the broken street ahead of you. Heading left from where you start, go around the corner, this standee is close to the edge of the street, and near the word ‘flare’. You will be able to see this standee while holding the focus button.
Barry Wheeler: The ‘memory’ of Sarah Breaker will open the church door for you. Turn left as you enter, and the standee is by a window, just before the first set of seats.
Cynthia Weaver: Using the searchlight on the three floating ‘bridge’ words will create a train car for you to use to access the next part of the level. When you drop through the train car, head to your right, and the standee will be right by the edge of the rocks.
Tor Anderson: After exiting the areas with the spontaneously flashing light poles, and before entering the lumber yard, turn right while facing the wrecked machinery leading into the next section. This standee is standing against the rocks in a corner.
Alice Wake: This final standee is found after dropping out of a warehouse room filled with ominous mist and red gas tanks (and of course, some enemies). There is a memory you can activate of Alice talking to Alan, and Alan will then remark that he has no idea how long ago he had saved Alice. From here there are two floating ‘bridge’ words. Head to the one furthest away and turn right. Alice’s standee will be by a few crates.
