Telltale Games has compiled all 19 episodes and associated side stories of "The Walking Dead" in one single package called "The Telltale Series Collection."

The collection — which will consist of "The Walking Dead: Season One," "Season Two" and "A New Frontier," as well as the anthology "400 Days" and the three-part "Michonne" miniseries — is a major visual upgrade from the earlier releases. Below is the reveal trailer for the upcoming collection.

Telltale has released a side-by-side screenshot to compare the original episodes to the ones in the collection, showing remarkable enhancements in color, lighting and clarity.

The new collection will arrive before game developers release the fourth and final installment of "The Walking Dead" video game series, which is due out in 2018. Telltale shared in the official announcement that it has enlisted the help of writer Gary Whitta to be a story consultant for the upcoming episode.

Whitta, who is famous for writing the films "Rogue One: A Star Wars Story" and "The Book of Eli," also oversaw the narrative development of the critically acclaimed video game's first season. It is where players first met Clementine, who in the middle of a zombie apocalypse found a father in a man named Lee. The exceptional storytelling earned it a number of Game of the Year awards.

Talking about his return to Telltale, Whitta said collaborating with the game developer for "The Walking Dead" season one is among the highlights of his career.

"Clementine has become not just one of the most compelling characters in the Walking Dead pantheon but one of the great video game characters of all time. I hope we're able to do justice to her and to her millions of fans," he added.

"The Walking Dead: The Telltale Series Collection" will be out on Dec. 5 across North America and Europe for PlayStation 4 and Xbox One.
