Finally, developers of We Happy Few [Official Site, GOG, Steam, Humble] from Compulsion Games started working on the Linux version, and they plan to be ready on or shortly after the release of the game which is scheduled for April 13 next year.

They posted an update on their Kickstarer page:

Hey guys! I've been working in the shadows for a while now, but since this is my first weekly: Hi! I'm Maarten, working as a freelance programmer, mostly tasked with engine support. That means my stress levels are *slightly* lower than those of the other programmers, and I get to work on some fun stuff! :) You may know me from such features as Video Support or Community Localization, but this week I'm hacking away at the Linux build for We Happy Few. Good news for our Linux fans, we're making good progress there. We sorted out all compilation issues, and are now fixing third party lib per lib. It's a cumbersome process, between switching to/from Linux, toolchain mismatches, having to figure out each lib's build process, etc - but hey, the thrill of the challenge is what we're programmers for, right?

It will be interesting to see how it will progress. So far their communication has been superb, and hopefully they’ll continue that trend for their Linux work too.

From their press release:

We Happy Few is the tale of a plucky bunch of moderately terrible people trying to escape from a lifetime of cheerful denial. Set in a drug-fuelled, retrofuturistic city in an alternative 1960s England, you’ll have to blend in with its other inhabitants, who have their own set of not-so-normal rules. Currently announced for Xbox One, Windows, Mac and Linux, We Happy Few is currently on Microsoft Game Preview / Steam Early Access. The Mac and Linux version will arrive shortly after the final release of the game.
