This is version 2.0 of the Clan Quest Mod. Changes include updates to UP and CE, more mods integrated into the installer, and two new quests / cut scenes. Just unzip the file and run the installer. Reference the packaged readme, for more details.
Please note that there is a typo in the readme packaged with the file. When running the installer, and asked to point to your Vampire folder, you need to point it at the Vampire directory underneath the Vampire install directory. The typical install path then should look something like this:
C:\Program Files\Activision\Vampire the Masquerade - Bloodlines\Vampire\
C:\Program Files\Steam\steamapps\common\vampire the masquerade - bloodlines\Vampire\
Vista 64 bit:
C:\Program Files (x86)\Activision\Vampire the Masquerade - Bloodlines\Vampire\
