The BBC has released a free online version of Infocom's classic PC text adventure The Hitchhiker's Guide to the Galaxy, commemorating the 30th anniversary of the game's initial release.

Designed by "Hitchhiker's Guide" author Douglas Adams, Infocom's game mixes humor, sci-fi, and frequent player death for an experience many regard as a high point in the text adventure genre. The BBC's latest adaptation follows up on a previous 20th anniversary re-release, and boasts improved in-game navigation along with a virtual keyboard suited for touch screens.

If you plan to play through this one, remember to save frequently. That bulldozer is a killer.
