Don't panic! Hothead Games uses the occasion of Towel Day to announce a "new edition" of The Hitchhiker's Guide to the Galaxy. Presumably this is some sort of game, but details are pretty scarce at this time, even on The New Hitchhiker's Guide to the Galaxy Website. They offer this image and the following explanation:

Hail people of Earth! Megadodo Publications is pleased to announce that we are working with the interactive entertainment development team Hothead Games to bring The Hitchhiker’s Guide to the Galaxy, the standard repository for all knowledge and wisdom, to the farthest uncharted backwaters of the unfashionable end of the Western Spiral arm of the Galaxy. This new edition of The Guide will be available not only on your planet but also on all nearby systems including Alpha Centauri.

"We're super excited to be involved with such a legendary creation as The Hitchhiker's Guide to the Galaxy. The quirky and hilarious universe that Douglas Adams created became an instant classic for so many. All the hoopiest froods here at Hothead jumped on the chance to work on the project”, commented excitable Hothead human, Joel DeYoung.
