My game is launching on Steam soon and I am planning to make it free to play with optional DLCs to buy.
The official Greenworks Plugin does not have support for DLCs and I fear the "Steam4C2" Addon is outdated/not supported.
Steam is able to download additional files when a certain DLC is purchased, so I could just add a text file with some content in it and then check inside of the game if that file with the content is in the folder. If so, then activate the DLC.
That approach would be super unsafe and easily "hackable", so I would only take this as the last possible option. (I tried it and it works at least)
Is there any safer way you can do it or should I just buy the "Steam4C2" addon?
