Dan Smith's upcoming puzzle title The Spectrum Retreat sets players on a journey to discover the truth behind The Penrose hotel. The hotel is a strange place and not everything is as it seems. Now players won't have to wait long to explore the hotel for themselves — the title will be arriving on Steam next month.The hotel's art-deco appearance exudes a feeling of peace, yet it is also distinctly unsettling. That's because its corridors and guest rooms hide a series of strange colour coded first-person puzzles. Not only will you need to solve those puzzles to discover the true purpose of The Penrose, you'll also have to face the fact that they hold the secret to your past, and the reason why you're even there in the first place. There's no escaping them. Take a look at the new trailer below to see what you can expect. The Spectrum Retreat will arrive on Steam on July 13th for £9.99 / €12.99 / US$12.99.
