- The "KARA" short film lists a number of Kara's technological specifics and abilities. However, as the film is proto-canon, these cannot be automatically taken as truth for the later game. Among these are battery life ("making [her] autonomous for 173 years"), use as a sexual partner, and more.
- It should be noted, however, that Kara's biography in the game itself indicates that Kara's first signs of "technical difficulties" occurred on the assembly line, which matches the tech demo.
