So if you want to get your hands on some Telltale goodness, head on over the Humble Bundle website. The bundle runs until April 26, so there’s still 12 days left to get your hands on it, with more games still to be added (don’t worry though, you won’t miss out if you purchase before that happens).
For those unfamiliar with the Humble Bundle, here’s how it works. You pay whatever you want (providing it’s at least $1), and they throw a bunch of games at you. However, paying more unlocks higher tiers, which of course means more goodies. Not only that, proceeds get split between the developers, a charity of your choice, and Humble Bundle themselves, with you able to decide who gets what.
