No Hit At All, or commonly known as NHAA, is a player created Singles Moving Screen mode with the map most commonly set to Reverse Demolition where players do not fight each other. The purpose of this mode is to gain Carats and experience without having to put in the effort to win. Sometimes players who do not have good connection resort to this mode. Players tend to socialize in these rooms or go idle whilst another player knocks their character to a safe location to prevent death.
Other players will also try to 'crash' the NHAA by hitting and killing people as they feel at which point others will gang up on them or avoid them from getting room master.
