Shrouded Citadel is an Augmented Reality dungeon adventure that you physically move through.
Using your phone as an AR portal, you must walk around sizeable dungeon locations to find the gateway to the next floor. Unique traps and puzzles await you on every floor with a variety of obstacles intent on stopping you.
While inside, you'll discover entities which will try to help you and others attempting to prevent your escape.
