The Walking Dead: 400 Days is a downloadable episode developed by Telltale Games in 2013, serving as a bridge between Season One and Season Two of the Walking Dead adventure series. Released on PlayStation 3, Xbox 360, PlayStation Vita, PC, and Mac, it is a point-and-click adventure spanning five distinct stories, each following a different survivor at various moments across the first 400 days of the zombie outbreak. The five narratives can be tackled in any order the player chooses, and decisions made within each story influence the others. The episode also connects to the broader series on both ends: choices carried over from Season One shape how events unfold here, while decisions made across these five stories carry consequences into Season Two, making 400 Days a meaningful narrative link within the larger Walking Dead continuity.

Storyline

With most of it based on a truck stop called Gil's Pitstop on a Georgia highway, "400 Days" tells five linked stories; each taking place at different points in time and from the point of view of a different survivor, from one day before the undead apocalypse to day 400. The five stories can be played in any order and will change based on the choices that you make. Echoes of the choices you made in Season 1 will carry over into "400 Days" and the choices you make in "400 Days" will resonate into Season 2. At the end of "400 Days", the stories are wrapped up, and leaves a few hints towards what we can anticipate to see from Season 2.
