Telltale Games revealed The Guardians Of The Galaxy during The Game Awards but nothings else about the game was revealed. While the studio is yet to reveal details about the game, it seems that Guardians Of The Galaxy Release date has been leaked by an online retailer.
According to the listing on GameStop, Guardians Of The Galaxy Release date is April 25, 2017, for the physical version of the game which is priced at $29.99 which presumably includes the season pass too.
However, usually the physical versions of games developed by Telltale are available some time after the first episode is released. As the first two episodes of The Walking Dead: A new frontier has been released but the physical version of the game will be available in February.
There is also a possibility that it is just a placeholder release date for Guardians Of The Galaxy. So until Telltale Games itself announces the release date take this as a grain of salt.
Guardians Of The Galaxy is not the only game based on Marvel comics in development as Insomniac Games is developing Spider-Man for PlayStation 4. The game was announced during E3 2016 with an amazing trailer but no further details have been unveiled.
However, story details for this PlayStation 4 exclusive Spider-Man game were leaked recently. According to the leak, Peter Parker owns Parker Industries and has a family too. His wife Mary Jane Watson died at the age of 26 is a near-horrific accident and Peter has her daughter under the protection of Cindy Moon.
Guardians Of The Galaxy game is currently in development for PC, Xbox One, PlayStation 4, and mobile devices.
