The Wiki page of the TWD Videogame Season 2/ 400 days dlc says this :

"At the end of 400 days, there will be a preview that will give you a few hints for what you'll see in Season 2."

I havent played the dlc ( still waiting for it on steam today ) But from what i heared from people who played it nobody mentioned that . So is there one ? A Preview for Season 2 of the videogame ?
