The walkers keep on coming. Season 2 of Telltale Games' The Walking Dead would continue the breakthrough adventure gameplay of the original.
Season Two continues the story that began in Season One. You are Clementine, a young survivor in a world gone to hell. The dead have risen to feast on the living, and the living cannot be trusted.
The story you experience in The Walking Dead Season Two is driven by the choices that you make. Because of that, your story could be very different from someone else's. If you played Season One and the DLC episode '400 Days', the choices you made there will affect Season Two. You don't have to have played Season One or 400 Days, however, to play through and experience The Walking Dead: Season Two.
