December

December is a reprogrammed Operator that guides Morgan Yu through the Talos-1 and appears in Prey (2017).

Overview
Unlike January, December encourages Morgan to escape by using Alex Yu's escape pod. If you are too late December will be destroyed by an unknown assailant, but its body can then be looted for the code for Alex's safe. However if you are in the Neuromod Division when December is destroyed, you see that the assailant is January, who claims that December was either a malfunctioning Operator or a work of Alex's.

Trivia

 * If January is destroyed by the player, early in the game or before going to the Neuromod Division. December will live and contact the player again after they retrieve Alex's suite key. And after the player finds the key to Alex's escape pod, Morgan will encounter December again by the escape pod and self-destruct, after telling Morgan that it has uploaded the data to Morgan's transcribe.
