Gamers and fans of Steam platform this material design wallpaper is for you feature here and optimized below in 4K, HD and wide sizes for customize any phone, tablet and desktop screen
First work made by Feven Kitsune (nickname🙂), shared on https://www.reddit.com/r/ultrahdwallpapers and from there, by his courtesy under CC By-Sa license here on gallery. If you're familiar with the Steam Community and like material design, probably you'll like this 4K image created in Blender (open source 3D content-creation program). Here on gallery, I've optimized it for fit in mobile devices. Personally, I like this version of the Steam wallpaper, but Feven made another version which is available here imgur.com.
