Nonstop debate is one of Danganronpa
class trial minigames included in all of the main games.
After you select
Truth Bullet (Mouse Wheel) found in Investigation period before the trial, you find weak spot at other people's statements and shoot (Left Mouse Button) this contradiction.
While playing
Nonstop Debate, white noise may appear (Incidentally it's colour is pink.) Which you have to shoot with Silencer (Right Mouse Button).
Sometimes you must absorb (Hold Left Mouse Button) other people's weak spots and shoot it at different people's contradictions.
You must of course listen carefully durning trial AND investigation or else you might not be able to clear it without trouble.
Example:
Girl E:
Heya, still got trouble with that debate?
Guy F: I just don't know how to
clear it y'know.
Girl A: Nonstop Debate you talking about? I can help.
