The gorgeous film noir stealth game, Calvino Noir, is out on iOS.
The game is about a revolutionist plot, and set in the 1930s European criminal underworld. You'll control a bunch of characters, who all work together to overthrow corrupt officials.
That generally involves sneaking about architecturally sound buildings, knocking out guards and snatching used info. You can use stealth or brute force to get by - up to you.
There's also a fully voiced, rich mystery plot. And that moody noir vibe, which is powered by Apple's Metal tech.
Calvino Noir needs an iPhone 5S, iPad Mini 2, or iPad Air or better to play. It has controller support and in-app purchases to by acts two and three. The first act is yours for £2.99 / $3.99.
