Can Pyramids are another type of collectible in Alan Wake, often found in unexpected places. Unlike Manuscript Pages or Coffee Thermoses, Can Pyramids require interaction: you must shoot them down to register them as collected. They are usually stacked in precarious positions, making them a fun target practice challenge.
There are 12 Can Pyramids in total, with a few appearing in each episode. They are often hidden in less obvious spots, such as on high ledges, behind obstacles, or in secluded corners. Listen for the distinctive clatter when you shoot them down. Collecting all Can Pyramids contributes to an achievement and adds to the overall completion of the game. They don't offer any direct gameplay benefits but are a satisfying find for explorers.
