As of today, a new mission type known as the Newblood missions, will make its appearance. Each new character release will be accompanied by a series of 5 Newblood missions. 4 of these will use the characters within the release, while the 5th will carry a prize of 10 credits and will be unlocked on completion of the 4 other missions. These one-off missions are available for a period of 2 weeks and will be deactivated once the next Newblood missions become available (you will, however, be able to finish the missions you have already started).
