Klei Entertainment is selling its games for cheap on Steam right now, which means chunky discounts on turn-based stealth game Invisible Inc, co-op survival game Don't Starve Together and rhythm-based roguelike Crypt of the Necrodancer.

The Invisible Inc deal is the most eye-catching: it's $4.99/£3.74, which is level with the cheapest it's been. For that, you get one of the best stealth games around. Think XCOM but with more sneaking and you're not far off.
