Single segment runs for Perfect Dark
A single segment run is a speedrun where the player completes all stages in one sitting. Runs do not need to be on a clean game file. Control styles and other settings may be configured before the run is started.
Single segment speedruns fall under two categories: game time speedruns and real time speedruns.
Real time speedruns
Real time speedruns aim to achieve the fastest possible completion in real time, regardless of what the mission time is. The total time is the real amount of time it took from choosing Accept in the menu before Defection to starting the cutscene at the end of Skedar Ruins.
Game time speedruns
Game time speedruns aim to achieve the fastest total mission time in one play through, even if it takes longer in real time. The total time is the sum of all mission times.
