Half insane run & gun platformer, half homage to every bro-out action movie ever and all early access legend, Broforce is my tip for one of the very best games of 2014. Seriously, it's a hoot and a half, especially in 4-player cooperative action. The Humble Store will save you an extra £3 until 18:00 this evening.
Don't get mad, bro. Get Broforce.
