Telltale's The Walking Dead is pretty excellent, haven't you heard? If for some reason you have yet to experience the episodic zombie adventure, you're in luck. Telltale is making the first episode of the game free on iDevices.
The first episode can be accessed by simply downloading the base app off of the App Store. You can pick up episodes 2 through 5 for $4.99 each, or buy the "Multi-Pack" for $14.99.
In addition to the free taste of The Walking Dead, Telltale is discounting much of their iOS back catalog. For 99 cents each, you can get individual episodes of Back to the Future, Hector, Jurassic Park: The Game, Law & Order: Legacies, Tales of Monkey Island, Puzzle Agent, Sam & Max, and Wallace & Gromit.
