I know that game is the main feature, but I'm kinda disappointed at extras. Wallpaper and avatar are the same kanji sign, the soundtrack stands out, but that's the only interesting thing. Shogo is great game with superb artstyle (those mechs man, those mechs), I find the lack of artworks and good wallpapers disappointing.

I was disappointed too. It seems like there are no Shogo wallpapers in higher resolutions, only this kanji sign.
So I made my own wallpaper, by resizing and editing one of the original images.
I have a laptop so it's only 1366x768 but if anyone uses the same resolution, feel free to grab it.
