Hi, i want to download the game, but i have way to many different platforms as steam epic origin... and i saw something about downloading the game without using the galaxy app, how can u do it/there is any tutorial on how to download and istall the game and last patch without downloading the launhcer/galaxy app?

Go to https://www.gog.com/account

Find the entry for Seven; click on it to open a menu

Ignore the blue 'download and install now' button

Download the 'offline backup game installer' instead (you'll need the files marked 'part 1 of 2' and 'part 2 of 2')

Put both files in the same directory and run the one that's a .exe

You shouldn't need any of the patch files, but unfortunately the GOG version of the game is currently missing patches 1.3.2 and 1.3.3: see
