  • The presence of the CCCP Luna 23 probe allows the operational zone to be established as the southern portion of Mare Crisium.
  • In the novel Mass Effect: Revelation, it is stated that Luna was "terraformed". It would not be possible for Luna to gravitationally retain an Earth-like atmosphere for a geological timescale, due to its low mass. However, the issue was clarified by the game's developers; several of the moon's craters were "domed over", allowing localized terraforming of the surface.
  • Earth from the Moon
    When looking at Earth from the surface of Luna, a reversed image of North America (Mexico, U.S. West Coast) can be seen. This has since been updated in the Legendary Edition to a normal image.
  • A prevalent in-game wind can be heard, even though Luna's atmosphere is very negligible.
  • Luna is briefly mentioned in both Mass Effect 2 when EDI is first introduced if Shepard orders EDI to be shut down due to distrust towards AIs and in Mass Effect 3 if Shepard chooses to examine the second set of video-logs in Cronos Station during Priority: Cerberus Headquarters.
