"Protect Nova" is an objective in The Saboteur in Battleborn
Walkthrough[edit]
Time for another round of defensive play. Have one or two people by the terminal to protect it. The rest of the team should split between the two sides. Use the countdown time to get the Turrets built to help with defending the terminal.
When the waves start you will need to do deal with more Varelsi. There will be two groups entering. One on the Eastern and One on the Western. This is follow by another group coming in down the center. More Varelsi will come falling in from the ceiling over the course of this wave. You will encounter Varelsi Skulks, Varelsi Hunters, Varelsi Marksman and the odd Varelsi Veil Walker. Toward the end of the wave you will need to deal with Bomber Thralls coming down from the ceiling and rushing either the battleborn or the Constructed Turrets.
The second wave starts more with Thralls come out of the doorways that you can see in the lower area of the Southern portion of this chamber. You will see Evolved Thralls, Primal Thralls, Thrall Gunners and a couple more. Getting through them will lead you to face more Varelsi that will focus on the Battleborn. This can include Varelsi Channelers, Varelsi Veil Walker and many of the same other kinds you have encountered previously in here.
The third wave will come after you get through the remaining forces. Rebuild any of the lost turrets and traps and get ready for what is coming. The wave can start with Primal Thrall Bombers rushing in from the ceiling and the entrance in the Southern part of the room. Around the middle of the wave you will need to deal with Varelsi Malinger appearing in the middle of the room. Be sure the team immediately draws its attention away from the core. Focus fire on it with most of the team while the rest work on the remaining Varelsi in the room.
