Bentley's Hackpack is a standalone mini-game pack released to coincide with the North American release of Sly Cooper: Thieves in Time. Players "take control" of Bentley and have access to three of the arcade machines at Bentley's Arcade, which feature more challenging versions of the three hacking mini-games in Thieves in Time.
The game is available for $2.99 on the PlayStation 3 and PlayStation Vita via the PlayStation Store, and similarly to Thieves in Time, purchasing the PS3 version of Bentley's Hackpack will grant the PS Vita version for free. In January 2014, the game was also made available on the App Store for iPads, and the Google Play Store for Android tablets at the same price. On all four platforms, a demo is available to try some of the mini-games.
Characters such as Sly Cooper, Murray, Carmelita, El Jefe and some flashlight guards from Sly Cooper: Thieves in Time hang out at Bentley's Arcade in modern Paris on their off-time, suggesting that it is non-canon.
Three arcade machines are available to play on: System Cracker, Alter Ego and Spark Runner. Each arcade features 20 stages, each of which has five challenges for the player to beat (for a total of 300 challenges). Each challenge awards one token, and bonus tokens are sometimes awarded by unlocking certain levels. In total, each arcade machine can award a maximum of 111 tokens.
The tokens can be used to unlock the 65 prizes at Dimitri's prize gallery, which bears similarities to the treasure walls in Thieves in Time. The tokens are not spent, but each prize goes up in the number of tokens required. Unlocking the final prize will let the player use a secret arcade machine, which is actually a hidden entrance to the basement of Bentley's Arcade. In here, the Cooper Gang perform a concert to the metal version of the theme song of Thieves in Time as the credits are shown on screen.
Sly Cooper: Thieves in Time was planned to be released sometime in the Fall of 2012, but Sony pushed the date back to February to give it ample room to release instead of in the middle of a crowded season. By September, Thieves in Time was complete and ready to be shipped, so Sanzaru began working on Bentley's Hackpack in secret.
- The exterior of the arcade resembles Flynn's Arcade from the TRON series. The inclusion of a secret room behind one of the cabinets further increases the parallels.
- Some of the non-playable arcades are references to real life arcades and retro video games like Donkey Kong, Duck Hunt and TRON.
