There are a total of 23 AR Challenges and 6 Training Challenges included in Batman Arkham Knight and they can be found either at specific starting locations throughout the city or can be played directly from the main menu. Each of the AR Challenges must be unlocked, often through meeting specific gameplay or campaign progress requirements before you are able to attempt them.
Each of the 23 AR Challenges is rated, with the ability to earn one, two or three stars upon completion. Often, achieving a high enough score will reward you with a Waynetech Point (once only per AR Challenge). Accumulation of stars is also required for the following three achievements/trophies:
- **Sins of Youth** – accumulate 23 total stars in AR Challenges.
- **Fortunate Son** – accumulate 46 total stars in AR Challenges.
- **Absolution** – accumulate 69 total stars in AR Challenges.
