This week’s Humble Weekly sale has launched, and allows you to pay what you want for Zeno Clash, Zeno Clash 2, Killing Floor, and Dwarfs!? as well as their OSTs (Dwarfs!? excluded). Those paying more than $6 can get the fantastic strategy and Monkey Ball hybrid Rock of Ages as well as Rising Storm. Both of those come with OSTs, and as will all things humble, you can donate all or a portion of the proceeds to charity if you so desire. The games run the spectrum from first-person shooter, to first-person adventure, horror, and a digging game in the form of Dwarfs!?, so if you’re in the mood to try out a bunch of different genres soon, this is a good way to go about it. Everything in the bundle activates on Steam and comes with a DRM-free Windows download.
