Norwegian convicted mass murderer Anders Behring Breivik has threatened a hunger strike if prison authorities don't upgrade his video game system to a PlayStation 3, among other demands.

"You've put me in hell," Breivik wrote to officials in November in a letter obtained by Agence France-Presse, "and I won't manage to survive that long. You are killing me."

Breivik currently has access to a PlayStation 2 console, but he has reportedly been less than pleased with the selection of games available.

"Other inmates have access to adult games while I only have the right to play less interesting kids games," the 35-year-old kid-killer wrote. "One example is 'Rayman Revolution', a game aimed at three year olds."
