Inspector Dupin is back in another Dark Tales adventure! This time around you get to play as the master detective as he tries to solve the mystery behind the disappearance of Monsieur Mark Davies’ wife, Sara Davies. You’ll have to follow a mysterious and creepy black cat through dark alleys and into spooky mansions to uncover clues and track down the evil culprit.

These pieces fit together somehow...

You’re able to interact with the various detailed environments by tapping on an area you want to go to or examine, and then tapping on items to take an even closer look. You’re also able to view your inventory and current objectives via the static toolbar at the bottom of the screen. If you need a little help getting back on track there’s no need to worry because this special collector’s edition of Dark Tales includes a bonus strategy guide.

The latest Dark Tales adventure includes many hours of gameplay, and features a nice mixture of puzzles and hidden objects activities to keep things feeling fresh. It also includes a single Game Center leaderboard.
