Editing X-COM: Terror from the Deep (section)

==Aliens==

While the aliens and overall atmosphere of the original game was influenced by [[extraterrestrial life in popular culture]], ''TFTD'' has a darker theme influenced by the works of [[H.P. Lovecraft]], including the appearance of the [[Deep One]]s<ref>[http://ufopedia.csignal.org/usopedia/Deep%20One.html Deep One - UFOPEDIA (X-COM Terror From the Deep)]</ref> (one of the alien races, the Tentaculats, is even described in-game as "not even the depths of a Lovecraftian nightmare could spawn such as this indescribable creature"<ref>[http://ufopedia.csignal.org/usopedia/Tentaculot.html Tentaculot - UFOPEDIA (X-COM Terror From the Deep)]</ref>). The game has eleven fictional races of alien beings. Each race has various strengths and weaknesses, and some races are dependent on other races. 

The aquatic aliens came to Earth on a large ship that crashed into the ocean 65 million years ago and supposedly caused the [[extinction of the dinosaurs]]. Many of the races from ''Enemy Unknown'' parallel these races, and some are supposed to have common ancestors. Several of the races have some source in Lovecraft's [[Cthulhu Mythos]], and their main base (the [[mothership]] into the [[Sigsbee Deep]]) is named T'Leth,<ref>[http://ufopedia.csignal.org/usopedia/T%27leth,%20the%20Alien%27s%20City.html T'leth, the Alien's City - UFOPEDIA (X-COM Terror From the Deep)]</ref> a reference to [[R'lyeh]], a submerged alien city from Lovecraft's short story "[[The Call of Cthulhu]]" ([[Cthulhu]] itself is also referenced there in the form of the chief alien in The Tomb room which is the game's final objective).
