Unlocks every mission temporarily
Every mission stays unlocked until you quit the game. The locks return when you start it again.
The mission options of the cheat menu let you skip the easy parts of the long trails and jump straight to the missions you love. Unlock All Missions removes every lock and offers two ways to do it: The temporary unlock lasts until you quit the game, while the permanent unlock is written into your saved progress. Reset All Missions wipes your progress and starts the missions over, and it shows a warning before doing so.
Most codes here need cheats turned on first. See the section on how to open the console.
