Rules
Streaming is generally not required, however for larger races it may be enforced. All officially released versions of the game are legal for racing. Runs must be performed on the vanilla game, meaning no mods installed such as custom entities, objects, maps, textures, music, sound effects etc. and without the use of developer tools such as the debug menu and quicksave/quickload. Race rules mirror the official leaderboard rules, so if you'd like a more in-depth coverage of the rules, check them out on speedrun.com.
