A spoiler is when we tell you something about a videogame which you don't know yet and you probably don't want ruining for you, for example that Aeris dies in Mario Kart: Double Dash!! or that to kill the last boss of Metroid Prime you have to shoot it loads.
Nobody gets a world record on their first run through a game. Because Speedrunwiki deals entirely in advanced videogame techniques leading to speed runs and high scores, we assume that you will have at least a passing familiarity with the games we cover before we begin. We will assume you know the plot. Therefore, articles here are sure to contain gratuitous plot spoilers without any kind of warning. This, here, is your global spoiler warning for Speedrunwiki.
If you're looking at the article for a game that you haven't already beaten several times over, then you're on the wrong site. Try GameFAQs.com.
