This is a replacement for Blaze's main menu art, which in my opinion looks nicer.

To install this mod you got to use SOR4 Explorer.

After loading SOR4 Explorer, and reading the game files, navigate in the left panel to: / > gui > menus > mainmenu
Uncompress the mod file somewhere at your hardrive.
Drag the *.png file from the mod folder and drop in SOR4 Explorer right panel.
In the top right corner you will see a message saying 1 sprite was replaced. Apply.

Note: I'm adding to the download section the original art, just in case you want to revert back, without removing all your mods.
