OSLO -- Anders Behring Breivik knew it would take practice to be able to slaughter dozens of people before being shot by police. In a chilling account, the far-right fanatic claimed yesterday that he sharpened his aim by playing the video game "Call of Duty: Modern Warfare" for hours on end.

Breivik told an Oslo court he also took steroids to build physical strength and meditated to "de-emotionalize" himself before the bombing and shooting rampage that left 77 people dead. He figured he had no more than a 5 percent chance of not being killed by police.

His lack of remorse and matter-of-fact description of weapons and tactics -- he even considered using a flame thrower -- were deeply disturbing to families of the victims, most of them teenagers.

"They perceive him as evil and dangerous and reopening wounds," said Mette Yvonne Larsen, a lawyer representing the bereaved. "It's one thing to read explanations, it's quite another to hear a person present such a message," she said. "I am personally quite shocked."

Breivik testified that he prepared for his attacks by cutting off contact with the outside world and devoting himself to video games. -- AP
