Funded through Kickstarter and now Greenlit, Grail to the Thief is an interactive audio adventure for Windows, Mac and Linux that can be played using only sound. However, even though it’s been designed with the needs of the blind and visually impaired in mind, the game can be enjoyed by everyone.

Players will become immersed in an experience in which he or she will always be fully aware of what’s happening through the use of voice-overs, sound effects, ambient sound and music.

Grail to the Thief is a nostalgic throwback to childhood favorites such as Zork, The Hitchhiker’s Guide to the Galaxy, Day of the Tentacle and Grim Fandango. It also draws inspiration from old BBC radio dramas and the movie Time Bandits.

The game stars Hank Krang, a dirty thief from the near future. A poker game nets him a self-aware time machine called the Time Excursion Digital Interface, or TEDI.

Being the nefarious type, he decides to use TEDI to travel through time and steal priceless artifacts, and travels to Arthurian times in search of the Holy Grail.   Grail to the Thief will be available for PC, Mac and Linux; stay tuned for a firm release date.
