Telltale Games is offering the first episode of its critically acclaimed Walking Dead video game free for download from the App Store for a limited time.

Debuting in April, the episodic role-playing adventure game takes place in the same fictional setting as The Walking Dead comic series, and centers on an original character named Lee Everett, a university professor and convicted killer who rescues and cares for a young girl named Clementine in the wake of the apocalypse. Familiar characters like Glenn and Hershel also appear in the game's five-episode first season.

Episodes 2 through 5 of The Walking Dead: The Game can also be purchased in-app for $4.99 each, or $14.99 in a bundled Multi-Pack. Watch the story trailer below.
