Starfield - Walkthrough [Part 23] Mantis - Part 2

The room with all the turrets is a puzzle. I thought you had to hack to door initally but the tiles on the floor are buttons. You need to spell out "TYRANNIS". I did it a few times before I saw the button on the stairs that you have to press after you complete it. It is also possible that buttons are a way to keep the turrets from shooting at you and if you take them out you can simple press the button. Not sure to be honest.
