And just exactly what has Starbreeze Studios been up to these days you ask? Well, the busy and super-talanted developer has been collaborating with Swedish film director Josef Fares on an upcoming digital-only fantasy game headed for the PS3, Xbox 360 and Steam this spring and published by 505 Games. Brothers: A Tale of Two Sons lets you control a pair of siblings with a single controller as they try to find a cure for their ailing father in a nicely detailed stylized fantasy world. Check out the teaser above and the short walkthrough clip below to see how the game will play. This one looks quite cool and hopefully will gain a strong following and not get buried in the rather large online game libraries on PSN, Xbox Live and Steam. As always, we shall see…
