Destroy a mission?

[Smokeynz]

public virtual void OnMissionLoaded(int missionNumber)

There is also the above available, which may allow you then to list the mission number and mission name.

noting each time the same mission name is loaded it gets a new sequence mission load number so you need to know both.

However as Kodiak notes only the ai or objects loaded within the mission need killing off. You may be able to reference all objects or ai associated with the load mission number and destroy all.
