As with all Humble Bundles, customers pay what they want for the games and also decide how to allocate their purchase dollars between developers, charities and Humble Bundle.
This means that anyone purchasing Humble Indie Bundle 15 can opt to allocate their payment to WLT. Bundle 15 includes indie games such as Goodbye Deponia and Q.U.B.E.: Director’s Cut. So far more than 100,000 bundles have been sold. Purchasers of others games from Humble Bundle’s online store can also choose to donate to WLT.
One of WLT’s most generous corporate supporters, Humble Bundle has donated more than £500,000 to WLT since May 2012 and more than US$50 million to charity overall.
Humble Indie Bundle 15 is on sale until 7pm in the UK on Tuesday 13 October 2015 (11am Pacific Standard Time).
