Telltale has made the first episode of "Batman: The Telltale Series" free until November 7th, 2016. Visit the game's steam page (http://store.steampowered.com/app/498240/ ) and click on "Download Demo". Good luck with playing it though. According to many user reviews the game lags a lot in general. And some users have got an error message which Telltale hasn't solved yet.
