The Walking Dead: Episode 4 is now lurking in the iPhone and iPad's shadows. Telltale Games revealed the fourth episode of its zombie-ridden series is live on the App Store within the Walking Dead: The Game app, priced at $4.99.

The survivors have one more episode to make it through, with the concluding 'No Time Left' slated to release this month. Telltale hasn't yet confirmed any final dates, or whether or not a November release applies to all platforms. Meanwhile, PS3 and Xbox 360 discs of the complete series are hobbling their way onto retail shelves on December 4.
