How do I get XP?
You get XP by successfully completing a mission. The whole amount of XP depends on how well you did. The faster your travel time, the more XP you get, and the duration you need for a mission, for example, is also linked to XP. This means that in addition to the general XP that a mission offers and that you can see on the map in the description before the start of the mission, you can also receive further XP through your approach and your individual success.
