So I found the right asset "\Blacksad_Data\StreamingAssets\assets_data\2172dc1d-d264-45aa-a94c-231bf3de6baa" file with the English localization, export the ScriptText using UABEA and changed only one sentence “new game” to “play” for the test
Then upload the edited ScriptText to the asset from which I got it
and the problem after that is that the game starts to run and just goes endless loading
