I used one of my submissions for the screenshot challenges as a steam custom background for the game, and thought someone might like to use it as much as I do. Really makes me want to launch the game everytime I see it! If anyone is wondering how you do this, just right click on the background area and click “Set Custom Background”. You can also adjust the logo position (like I did in the example below) to make it fit the screenshot more.
Here’s what mine looks like.
The screenshot itself if you would like to use it.
Maybe some other people have some custom backgrounds they would like to show off in this thread?
