Mariana Arias

Mariana Arias is a climate engineer working on Talos I during Prey (2017).

History
She manages to escape the Typhon outbreak by going through the exterior. Unfortunately, the airlocks were locked out during the outbreak and her attempts to get back inside were failed. She went hysterical after catching glimpses of the Technopath that was haunting her.

Prey (2017):
Morgan can find her corpse along with a Q-Beam in the Talos I exterior. The Technopath's presence nearby suggests that either she was killed by the Technopath or died from a heart attack
