* CanonName: The official names for Aida and Isaak are [[https://www.beyondunreal.com/articles/unreal-2-the-forgotten-game/?page=4 Aida Shen and Isaak Borisov]].
* WhatCouldHaveBeen: This game has a LOT of content cut from the game, as seen [[http://liandri.beyondunreal.com/Cut_content_of_Unreal_II here]]. The final game would have weighted 8GB, which was A LOT for its time (in comparison, sister game Unreal Tournament weighed 3-5gb without any additions). The special mention in this area is the multiplayer part, which was cut because ''Unreal Tournament 2003'' made it redundant, along with rushed development.
** For example, one early preview blurb seen in magazine promises features such as dynamic conversation, HumanoidAbomination enemies called the N (in which only exists three in the universe however its constantly teleporting if sufficiently injured), EldritchAbomination enemies called the Strider (which able to join and turn into new form of enemy), and jellyfish like alien race called the Shian (with concept artwork). None of the stuff appears in the game, and [[DummiedOut while files pointing to Shian exists in the game files, opening it reveals nothing.]]
