Quakecon attendees, don't forget to make sure your blood is topped off to participate in the American Red Cross blood drive for an official The Evil Within chill pack. "The Good Within Blood Drive" will take place at the Hilton Anatole Hotel in Dallas, Texas (the same location as the convention) on Friday, July 18 and Saturday, July 19.

Those seeking to participate in the exsanguination can sign up in the Topaz room. You must be at least 17 years old and meet certain other requirements. QuakeCon 2014 will take place July 17 - 20 and participants can now enjoy the exclusive DOOM reveal with light-headed joy.
