The Walking Dead hasn’t exactly stumbled out of the blocks. Telltale’s latest episodic adventure — based on the popular comic book series of the same name — has already surpassed one million sales just three weeks after release, making it the fastest selling game in the developer's history.
The figures span PSN, XBLA, PC and Mac. There are four more episodes still to be released, with the next due out at some point in June. It's probably safe to assume that the current series of The Walking Dead won't be the last.
