The Humble Bundle Android 8 is available for whatever money you wish to throw it's way!
Best of all, it includes 6 cross-platform (Linux compatible) games and most likely will add a few more soon, as is the tradition of the Humble Bundles.
Games currently in the bundle:
- Little Inferno
- Gemini Rule
- AaaaaAAaaaAAAAaaAAAAaAAAAA!!! for the Awesome (yes that's an actual game title and one that most notably caught my eye)
- Jack Lumber
And for those that pay over the average purchase price:
- Hero Academy
- Anomaly 2
And of course, all the games have DRM-free downloads as well as redeemable Steam keys (the latter if you pay more than $1).
If you wish to support charity and developers (and of course Linux gaming), head on over to the Humble Bundle site.
