The Ark:

4000 humans, 3000 male and 1000 female, escaped the end of life on earth on the best spacecraft that early 21st century technology had to offer. This group, as large as the Ark could support, was made up of the best professionals that it could be guessed would be needed. You, /b/, will be controlling this last remnant of humanity on their exodus. Placed in cryogenic sleep, your people have rocketed through space on a preprogrammed course for over a hundred thousand years, bound for a somewhat earth-like planet thirty light years away. Almost nothing is known of this planet except that it has a nitrogen-oxygen atmosphere and its surface is approximately 64% salt water, 2% fresh water (including glaciers) and 34% land.

As the spacecraft finally lands in the northern hemisphere of the planet and the automated systems wake the frozen travelers, they emerge to see a landscape that is at once alien and familiar. Like Earth, and yet unlike. The survivors of the apocalypse must decide what to do first.
