Go here to get it: www.Wolfire.com/Humble
Also, everybody who buys the bundle will be able to buy the rest of the Penumbra series at a 75% discount ($5 that is)!
I think this is a pretty good offer and also an opportunity to do some good :) If you think likewise please spread the word! Remember, it will only last for 7 days!
Please Note: The 75% discount ends the same day that the Bundle ends!
