Bethesda opened its inaugural E3 press conference with a rather impressive, and astoundingly gory, demo of its reboot of the DOOM franchise. Arguably one of the most exciting announcements, though, was of a feature which allows you to create and share your own maps and levels.

Titled Snapmap, this new mode gives you what appears to be a remarkably robust set of tools with which to make your insane ideas come true. What's more, you can alter the very logic which dictates the gameplay, which means you'll be able to generate your own specific game modes. Neat.
