Soon after this discovery, rumors spread, primarily due to the mainstream media at the time, that Klebold had created a custom level that was an exact replica of Columbine High School in which to practice for the attack. Not only did the boys play the game with an almost obsessive level of passion, it was discovered that they had created their own custom levels. Shortly after the shooting, it was discovered that both Harris and Klebold were avid fans of the first-person shooter Doom. On April 20, 1999, two senior students (Eric Harris and Dylan Klebold) at Columbine High School in Columbine, Colorado, used explosive devices, shotguns, and carbines to murder 12 students and a teacher, as well as injure an additional 21 people.
