The Humble Jumbo Bundle 2 is now available on a pay-what-you-want basis and comes with The Incredible Adventures of Van Helsing: Complete Pack, Deadlight and Galactic Civilizations II: Ultimate Edition. If you pay over the average ($6.14 as of this writing,) you get Terraria, The King of Fighters XIII: Steam Edition and Crusader Kings II (which comes with 3 DLC Unit Packs.) Finally, if you pay $15 or more, you unlock the Age of Empires Legacy Bundle.
Paying $1 more, means that all the games you get are redeemable on Steam and as usual, part of the money goes to developers, the Humble Bundle team and charity (in this case, the American Red Cross and Child’s Play Charity.)
