[Update] The mid-tier now includes three more titles: The Bridge, Race the Sun, and Monaco: What's Yours Is Mine. Surprisingly, the cost of the mid-tier has dropped slightly to an average of $7.76.
[Original] The number of Humble Indie Bundles has reached a dozen, and it's still rolling out the hits.
This time around in the Humble Indie Bundle 12, you only have to pay a measly dollar to get SteamWorld Dig, Hammerwatch, and Gunpoint for Steam. The next tier is currently at $7.78, with it rising if more people purchase the bundle at a higher price point, which includes Gone Home, Luftrausers, and Papers, Please. A usual more games will be coming soon, so check back soon to see what other games will be rolled into the package before purchasing this bundle outright.
For the higher tier of $10, you'll unlock early access to Prison Architect, but there is a higher premium tier at $65 by way of Fangamer, where you'll score a special issue of HIB Informer Magazine, a HIB 12 Super Shirt, a set of pins with the Humble Bundle logo and Arstotzka Crest. It also comes with a vinyl record, a HIB 12 Shareware 3.5" floppy disk (not a joke), and worldwide shipping is included.
And of course you can donate to the Electronic Frontier Foundation and Child's Play Charity.
