I have to give it to The Game Kitchen, they are not an easy studio to predict! They went from making point & click adventures to grim yet stylish Metroidvanias, and now they're working on what looks like a Commandos inspired real-time, stealth focused tactics game!
Set in an 18th-century Spanish monastery, The Stone of Madness will put you in control of five prisoners, each with their own unique skills and resources. However, unlike games like Commandos where you play with a team of hardened veterans, your characters in The Stone of Madness aren't exactly the most... stable bunch. So not only will you have to navigate obstacles and deal with all sorts of enemies with them, but you'll also have to manage their phobias and their dwindling mental health.
I wouldn't hold that against them though, because it seems like the monastery is full-on haunted! During the day things are mostly normal and you'll only have to dance around guards and other prisoners, while at night you'll have to contend with significantly more paranoid security, as well as a variety of paranormal threats that may suddenly appear and push your characters over the edge - both figuratively and literally!
As for the sort of style and atmosphere The Stone of Madness is going for, that you can check out through the story trailer below. Have a gander:
Additionally, The Stone of Madness currently has a free demo available thanks to the ongoing Steam Sale. So if you're like me and you love these types of real-time stealth/strategy games, I'd highly recommend giving it a look.
You can check the demo out before it goes away on October 21st, as well as learn more about The Stone of Madness, over at Steam. Enjoy, and here's a couple of images to pique your curiosity:
