The demo will allow players to sample a portion of campaign mode over two stages, one set in the Shibuya's Spain-zaka area in the lower city and one in the Shinjuku Station-like area of the upper city.
The demo will offer voice command support, where you give voice-based commands to your support characters. However, it will not support online play.
