,
if its the latest one,I did open it with assetgripper,now i am confused,and do not know what to do next.
you do click on file > open folder > select the game's installation folder > wait for it to extract everything > click export > export all files to dump the game's contents to a folder
By game,s installation folder,do you mean Vessel Tactic(containted everything in it) or Vessel_Tactic-Data?or Vessel Tactic.zip?
the unzipped folder that comes out when you unzip the game's downloaded file, so it would be called "Vessel Tactics"
