Pulsatrix Studios are working on FOBIA - St. Dinfna Hotel, an upcoming psychological horror and it appears a number of readers are excited about this one. We've had quite a few emails and notifications about it, as they recently put up a demo with Linux support on Steam.
Fobia is a first-person experience that focuses on mixing together environmental exploration, a little survival and some puzzle solving. You assume the role of a young journalist named Roberto, investigating supernatural events to get a bit of a career boost which leads you to the Santa Dinfna Hotel.
You can see the original trailer below. It's in brazilian but YouTube's captions do a good enough job for me:
For some actual Linux gameplay, you can check out this video from Xpander.
It appears they're also running a crowdfunding campaign on a platform called catarse, which interestingly is open source. Not as known as the likes of Kickstarter and IndieGoGo but nice to see some free and open source funding platforms. The FOBIA has another 42 days to hit R$50,000 (Brazilian real).
