Sudden Death (SD) mod icon
Miss a note and fail.
The Sudden Death mod is a game modifier that causes players to fail a beatmap upon missing a hit object or failing to collect a slider tick. This is useful for players who are going for a full combo (FC).

To be more specific, the Sudden Death mod will only fail the beatmap if any of the following happen:
The Sudden Death mod will not fail the beatmap if any of the following happen:
Unlike the Sudden Death mod's variant Perfect, the beatmap will not automatically retry the map. Instead, the player will be left with a normal failure screen upon missing.
This mod has the same effect across all game modes.
