The Walking Dead Game Season 3 Original 2016 Trailer

This was the trailer released at E3 2016 showing what the walking dead season 3 could have been like. And actually this is really odd to me because how the game is vs what this trailer depicts are entirely different, and the dates between the trailer and the release are only 6 months. So either they gave out an old trailer they made a long time beforehand and didn't bother making a new one, or they entirely changed the course of the game and rushed the changes over those 6 months.
