The countdown to Telltale's grand Walking Dead finale reaches zero today with the launch of the appropriately-titled No Time Left on all major platforms.

Picking up where the previous dramatic cliffhanger left off, Lee Everett (and maybe others, depending on your earlier choices) must head out into the zombie-ravaged streets of Savannah to track down 8 year-old Clementine and discover the secret behind the mysterious voice on the other end of the radio.

As with previous installments, No Time Left is available only as part of a full-season bundle for PC and Mac, or as a standalone episode for Xbox 360 for 400 MS points. The PlayStation 3 and iOS versions are available either as part of a season purchase or as a single-episode download.
