The latest Humble Weekly Bundle is a bit of a mixed bag in terms of both genres and quality, but if you stump up $6 (£3.67) for the second tier, you'll get the headline act. Deadly Premonition is shonky, bare-bones, incredibly weird and absolutely one of the best games of the last console generation.
You'll also get the Commandos Collection and Deadly 30, which I can both personally vouch for, alongside Lexica, Bridge Constructor Medieval, Battle Group 2 and The Book Of Legends, which I've never tried.
Alternatively you can just part with 60p for Lexica, Deadly 30, Bridge Constructor Medieval and Battle Group 2, which is cheap if potentially a bit of a punt quality-wise. Thanks to jaystan @ HUKD!
