Ravage uses a few different art assets for things like thumbnails, banners, etc. You are free to use whatever you like, but if you would like to carry the style of Ravage, then here's what you'll need.
The Ravage logo and various texts use the Weltron Urban font. It's a free font and is available here
The banner image at the top of this page is a modified version of this photograph (click on it for the full resolution version). It's a picture of some derelict buildings on Hashima (sometimes called Gunkanjima) which has a fascinating history and has been used in a few films.
