Titled Thicker Than Water, will be available next week.
Batman: The Telltale Series was somehow unique as a title among many developed and published by Telltale Games. The first episode released in August of 2016 and all succeeding chapters were released month by month.
With The Walking Dead: A New Frontier the situation is much different. Episodes one and two were released simultaneously on December 20th. Then we had to wait for a long time until March 28th for the third chapter. Fortunately, the fourth episode will release this month, on April 25th.
It was confirmed by Telltale Games, with the additional info that we should expect the trailer soon:
