A boss rush is a game mode built around a sequence of boss fights, typically with little downtime or exploration between encounters. It lets players replay the most demanding battles directly, and may track completion time or other scores on a leaderboard.
Boss rush is not a cybersecurity term, but it illustrates how a software feature can change what a system records and compares. When a mode uses online leaderboards, developers need to validate submitted scores and protect accounts and ranking data from tampering or abuse. Clear rules about eligible runs and settings help make comparisons fair and trustworthy.
