Humble Bundle offers downloads of its Humble Bundle 3-Game Indie Bundle for Windows, Mac, and Linux for whatever you want to pay. If you opt to pay the bare minimum of $1, you'll get Lethal League, The Beginner's Guide, and Galak-Z. That's $33 under what you'd pay for these games separately elsewhere.
If you pay more than the average, currently $5.82, you'll also get Lovers in a Dangerous Spacetime, Octodad: Dadliest Catch, and Super Time Force Ultra. Finally, pay $10 or more to also get Nuclear Throne. Your contribution can be donated to charity (Electronic Frontier Foundation and Child’s Play), the developers, or both. All games are available DRM-free and via Steam. Deal ends August 30.
