To be in the running to win, you have to submit a photo demonstratiing your support for the Red Faction. It must be a real photo - preferably of you. It must be taken in a public place - i.e. not your bedroom. And it must include, in some way, shape or form, the Red Faction Hammer logo - the symbol of the revolution (pictured above, and at higher res in the original post).
Oh, and here's that bloody great big hammer. There are only 60 of these in the world... and you could win one of them.
