Isaac Kleiner through the resonance cascade and the following two decades might have to do with, depending on his age (which doesn't seem to be attested anywhere), either having been part of the German Jewish diaspora which took place in the mid- to late 1930s, or being a first-generation descendant of someone who was. Although this encounter is scripted, when an Ichthyosaur is spawned using console commands or a mod such as Garry's Mod it also attacks the player in the same manner. Underwater, he is almost swallowed whole by an Ichthyosaur before being transported elsewhere. During the teleport malfunction ("harmonic reflux"), Gordon Freeman is momentarily transported outside of City 17, in midair. The Ichthyosaur also makes a single appearance in Half-Life 2. The speed and viciousness of the Ichthyosaur, combined with poor underwater visibility, limited choice of weapons and limited oxygen while underwater, make the underwater areas of Half-Life some of the most frightening parts of the game. They are often placid at first, but quickly become hostile, especially should the player take action against them. In Half-Life, Ichthyosaurs are encountered in several water bodies, including a flooded laboratory, the reservoir near the hydroelectric dam, the sewage areas, and one of the Nihilanth's chambers. However, there is evidence that Ichthyosaur specimens were kept for observation, as seen in Opposing Force. This is possibly the time of its arrival at the Black Mesa Research Facility, the creature being likely from Xen.

When the Ichthyosaur is first encountered in the Half-Life chapter Apprehension, a scientist remarks that while he has been told it was hauled from the Challenger Deep in the Pacific Ocean, he believes that the creature never swam in terrestrial waters until a week before. These creatures were prominently featured in Half-Life and its expansions, and it also made a cameo appearance in Half-Life 2.Īlthough the in-game creature is named after the extinct marine reptile group, the Ichthyosaurs, it resembles them only in its carnivorous ecology and its general size.

The Xen Ichthyosaur is an aquatic animal originating from the alien realm of Xen in the Half-Life game series.
