Mass Effect: Andromeda
Following the arrival of the Hyperion at Habitat 7 and its subsequent rub against the ominous energy cloud, Dunn argues with Alec Ryder over their next course of action, with Dunn believing that attempting to land on the planet would be a mistake. She later guides the Hyperion during its docking with the Nexus.
Captain Dunn can be found during the Hyperion's kett hijacking, fending off several of the hostile aliens before Pathfinder Ryder's sibling comes to her aid. Dunn would, in turn, distract the kett as he/she made their way to SAM node.
The Archon would later capture Dunn along with the Hyperion, abandoning the ship at Meridian while causing catastrophic damage to its systems. Dunn would go down with the ark in an attempt to save it, with her fate ultimately depending on the rescued Pathfinders.
Dunn's survival requires all three non-human Pathfinders to work together. The salarian Pathfinder's cooperation is assured regardless of who currently holds the role.
If the asari Pathfinder is Vederia Damali, or Sarissa Theris's secret was kept, they will work to protect Dunn. However, if Sarissa was disgraced but kept her title, Ryder must approach her, apologize, and ask for her help with securing Meridian. Otherwise, she will be unwilling to help.
There is no turian Pathfinder if Avitus Rix was not convinced to take on the role; in this case, Dunn's survival is impossible.
