"Activate self-destruct system" is an objective in The Saboteur in Battleborn
Walkthrough[edit]
This will trigger the final round of defending Nova to complete the mission. These waves will be very challenging to hold off and will take a good amount of coordination in many regards. Take the time to go around the area and build all the traps and turrets that you can. This will ease things up a little but not too much overall. Be sure everyone is ready with all their abilities before the self destruct is triggered.
