Get inside or the shield door will lock you out.
Don’t attack anything that has a shield on it.

<Player with stealth’s name>, please stealth around the back to get the terminal objectives.

If you get aggro: drag boss to the fire circles when they appear and move him around inside the circles until he’s stunned.
Saves me from typing it in each time. Feel free to use :D
