Set on Nukara Prime. This can be done from the pve queue or by visiting Nukara Prime itself located in the caves.
This is a Ground mission and you MUST equip and active your Environmental Suit. Without it, you will die.
NOTE: IF YOU DIE IN THIS MISSION DO NOT RE-SPAWN. YOU WILL NOT BE ABLE TO GET OUT OF THE CONTAINMENT AREA. WAIT FOR ANOTHER TEAM-MATE TO HEAL YOU.
This is a 5 player team. When you start the mission activate your Environmental Suit and then make your way to the console located at the back in the middle. Be careful to avoid the acid pools.
Activate the Console. The Project Leader will appear. This will be a large Tholian. Shoot at it until he disappears.
Once the Leader has disappeared the team then has to close the incoming portals and stop the Ensign Tholian's. Shoot down the portals.
Once again shoot at the Project Leader who has re-appeared.
Again, shoot down the incoming portals and defeat all Tholians. Watch out the Tholian Webbing as these will drag you into the acid pools.
Take down the Tholian Project Leader.
