The Devil May Cry demo is coming to Xbox Live and PlayStation Network next week, arriving in North America on November 20. As for Europe, it drops the same day on Xbox, but a day after on PS3. Capcom didn't mention a PC demo in its announcement.
The demo offers two missions, including a boss battle. After one completion it unlocks the special 'Son of Sparda' difficulty, which plays around with enemies' placements and behavior as well as making them tougher to beat
