There's two new Humble Bundles that are worth taking a peek at if you're after a bargain. The Weekly Sale includes Little Inferno, Super Hexagon and Natural Selection 2 as the base games, and paying over $6 will also bag you Hotline Miami, PixelJunk Monsters Ultimate and Critter Crunch.
The other bundle, which has been running for a couple of days now, includes Broken Sword 2: The Smoking Mirror, Bridge Constructor, Type:Rider, and Ravensword: Shadowlands as the base games, and paying over the average (just under $4) also means getting Kingdom Rush and Knights of Pen & Paper +1 Edition.
