Walking Dead Season 1: 400 Days DLC [Full Game]

Season 1 of The Walking Dead Telltale has a DLC called 400 Days, in which you see each character's perspective for the first 400 days of the zombie outbreak. I guess this is around the time Lee arrived. The characters you play can be seen in Season 2 Episode 3, depending on who left with Tavia, a character who found your group.
