The Humble Bundle has a habit of adding even more goodies to its bundle when a particular sale is going well. And apparently, its first Humble eBook Bundle is doing incredibly well, as the folks behind the organization have added an extra five eBooks to the already-stellar list of titles.

The five new eBooks are in addition to the seven that I wrote about one week ago today. If you pay more than the average, you’ll also get Randall Munroe’s xkcd: volume 0, Zach Weiner’s Save Yourself, Mamma! and The Most Dangerous Game, as well as Attack of the Bacon Robots and Epic Legends of the Magic Sword Kings, both collaborations of Jerry Holkins and Mike Krahulik, the guys behind Penny Arcade.

As always, you can split up however much you pay between the authors, the charities, and Humble Bundle itself.

If you’ve already purchased the Bundle before today at the above average price, then don’t worry: you automatically get the five books that were added today, without needing to purchase it again!
