Hitchhiker's started life as a BBC Radio 4 series in March 1978. The original scripts by the late Douglas Adams spawned novels, a feature film, at least three stage shows, a TV series and a collection of comic books - as well as various towels.
The game was devised in 1984 by Adams and Steve Meretzky from Infocom. Notoriously difficult and full of oddities, it was one of the best-selling games of its era.
The 20th-anniversary edition of the game launched on Radio 4's website in 2004, and more than three million moves were made in the game in its first three days of launch and more than 50 million moves had been played within six months. It went on to win a BAFTA for Best Online Entertainment.
The 30th-anniversary specially-updated version of the game will allow users to share their achievements with friends over social media via the official Twitter feed @h2g2game.
The game will now be in high definition, thanks to refreshed illustrations and graphics. It is web-based and will be accessible via Radio 4 Extra's website. Players will also be able to take the game on the move, as it will be compatible with tablets and other internet enabled devices.
Radio 4 Extra will also be broadcasting series one and two of The Hitchhiker's Guide To The Galaxy. It has been more than 10 years since these programmes were last heard on BBC Radio and they perfectly accompany the game. Actions within the game follow the plot of the radio series and some puzzles are only solvable by players with knowledge of the programmes and story.
The single-player game starts with lead character Arthur Dent working his way through a series of different challenges and zones. Players use a specially-designed keyboard to enter their commands and there are achievements to be won throughout the game by completing a series of tasks. This interactive work of fiction sees players visiting other planets, meeting aliens and robots, and creating (or losing) the plot, based on their decisions and choices as they progress through the game. It is renowned for its difficulty and it never misses a chance to kill players off in hilarious and infuriating ways.
Caroline Raphael, commissioning editor for Radio 4 Extra, said:
And later this month, the original Hitchhiker's cast will continue to shake up the Radio 4 schedule when they reunite for a special performance, broadcast live from the BBC Radio Theatre in Broadcasting House. Led by Simon Jones as Arthur Dent, they will be bringing to life the characters created for them by Adams in highlights from the entire Hitchhiker's saga. The actors will be joined on stage by a Special Guest Voice Of The Book - Adams's long-time collaborator and sometime flatmate John Lloyd, who co-wrote the fifth and sixth episodes of the first series and was associate producer of the TV version.
It takes place on Saturday 29th March at 10am as part of the Character Invasion event that will see some of the nation's best-loved characters invade Radio 4 and take over the airwaves. Tickets for the show can be applied for via this link. Please note that they will be allocated via a random draw. People can register for up to four tickets per household at any time until Thursday 13th March at 4pm. Other broadcasts that same day can also be applied for, but should you be successful in the draw you will only receive tickets for one session. It should also be noted that allocation of the free tickets does not guarantee entry.
