The Walking Dead's second-screen experience has just gotten a really cool facelift ahead of the show's Season 5 premiere.

The enhanced version of The Walking Dead Story Sync will gauge a user's responses and be able to tell them, based on their choices, whether they would have survived an episode — and the character to whom they are most similar.

Also new this season, Story Sync, which is a complement to the live show, will have a "Watch With" feature that will allow users to see the responses of celebrity participants during certain episodes.

"The new features have been in development since the end of last season" Mac McKean, AMC’s senior vice president of digital media and content told Mashable in an e-mail. "As we’ve learned what users and viewers are responding to and what is truly additive to their viewing experience, we’re able to add new features without being afraid that we’re steering people away from the show or distracting them.”

Based on usage, Story Sync is one of the most successful second-screen applications, according to the network, drawing more than 2 million unique participants during last season.

Before the revamp, the app focused on providing supplemental information on the story and characters, polls, and quizzes — all of which have been and continue to be developed with help from the show's producers, McKean said, "to make sure Story Sync matches their vision for The Walking Dead.”

The Walking Dead, which was recently renewed for Season 6, premieres Sunday at 9 p.m. ET on AMC. Viewers can start Sync as the live episode begins.
