I'll be creating a new profile background every few weeks. We're going to keep it more of a creative endeavor for now instead of focusing on creating backgrounds for specific games. We want to offer background art that's a bit more unique and exclusive to gamerDNA.
To change your profile background head to any page in your profile and click "SELECT THEME" in the upper right-hand corner. Scroll down a bit in the window that pops up and you'll see "Shooter #1". Click it to preview and press the "ALL DONE" button when your... well, all done :)
Woah! Nice one man :D How about a community challenge kind of thing where members can create backgrounds for the profiles and the 3 best are added. Just an idea (that's probably already been done and that I've missed) ;)
