Linux and Mac versions of the long-awaited Dreamfall Chapters: The Longest Journey will be released if the game’s official Kickstarter funding campaign receives over $900,000 USD in pledges, Red Thread Games has confirmed. The Norwegian developer announced the stretch goal and a number of others earlier today, as the adventure game sequel creeps towards its funding goal of $850,000 USD with twenty-two days to go.

In a campaign update, the team confirmed that both Linux and Mac support would be provided at the $900,000 USD – presumably an easy feat, given that the game will be built with Unity – and that pledge levels of $950,000 USD and $1,000,000 USD would see significant amounts of new content added to the game.

Dreamfall Chapters is the sequel to 2006’s Dreamfall: The Longest Journey, itself a sequel to the cult classic point-and-click adventure, The Longest Journey. The game is being developed by Red Thread Games, a studio newly formed by the series’ original lead designer, Ragnar Tørnquist, with the blessing of original developer-publisher Funcom, which is currently occupied with maintaining its MMO, The Secret World.
