The Nightcore mod is a game modifier that works in the exact same way as it's variant mod, Double Time, but also increases the pitch and adds a drum track to the background that — in 4/4 time — goes in the order of a bass drum on beats 1 and 3, clap on beats 2 and 4, and crash on beat 1 every 4 measures.
The score multiplier stays the same as it would with the Double Time mod enabled, and the beatmap itself is unaffected beyond what the Double Time mod will do.
This mod has the same effect across all game modes.
