Skin Installer - Version .80 The Half-Life Skin Installer was created to make the installation of skins and models a snap. There are over 350 custom skins/models for Half-Life and the number grows each day. To install such a large number of skins/models is no trivial task... each skin/model has a .mdl and .bmp file that must be placed in an appropriately named directory. What would normally take hours to do can now be accomplished in a few minutes with the Half-Life Skin Installer. Install an unlimited number of models/skins. CRC checks each archive for validity. Visual confirmation of installation success or failure for each archive. Automatically locates the Half-Life player directory. And much more...
