This mod replaces the skins for the base game tyrannosaurus and gives you the option to breed two varietals of the trex: a female and a male from The Lost World (1997). As a result, this mod alters the DinoList and FslHunt files as well as the matlibs (skins) files. The mod also changes the AI of each of these rexes so they will NOT fight one another to the death if they are in the same enclosure. This involves a slight change to the Trex and (new) Trex2 inx. files in the "Units" folder.
At the hatchery screen, both versions of the tyrannosaurus will appear as the female "Doe" skin in the display, but the second tyrannosaurus will actually be the vivid, green male rex: the "Buck" from TLW.
To install:
Simply download the available files and replace those in the "Data" folder inside your JPOG folder. As always, be sure to backup your existing files.
