The very generous gift of this free dynamic theme for Ghost of Tsushima comes hot on the heels of Sony Santa Monica releasing a whole bunch of free content for fellow first-party exclusive God of War.
In regards to Ghost of Tsushima, we know that the game will release on PS4 in Summer 2020 and just in case you missed the brand new trailer for the game which was shown at the latest State of Play, you can catch it below.
Happy holidays folks!
