Denial of Service Badge
From Paragon Wiki Archive
Description
You crept a bit too close to the danger zone and got burned.
How to Get
Attempt (and fail) to pass through the sonic barrier surrounding Praetoria. While there's no formally marked spot for trying this, not every rush into the barrier will get you the badge. Most spots just send you to the Hospital. If you get one of the right spots, however, you will be teleported to a safe distance...hopefully before your hit points finish running out.
Requires Going Rogue.
