Thorough exploration is key to uncovering all of Control's secrets. Revisit Areas: New abilities often unlock previously inaccessible areas. After acquiring Levitate, for example, revisit early sectors to find hidden ledges and rooms. Listen for Cues: Collectibles often emit a faint, ethereal hum. Listen closely, especially in quiet areas. Look Up and Down: Many secrets are hidden above or below the main path. Use Levitate to reach high ledges or look for destructible floors. Check Every Room: Even seemingly empty offices can contain a hidden document or a chest. Janitor's Office: Ahti's office often has new side quests or hints about hidden areas. Always check in with him. The map will highlight areas with undiscovered collectibles once you've cleared the main objectives in a sector.
