How to Install Snowbank
To install Snowbank just drop snowbank_v1.nob into your Vampire directory, which will most likely be in the directory:
C:\Program Files\Vampire The Masquerade - Redemption\
Then when you load up a multiplayer game you should be able to see Snowbank!
The map files by the way go into....
C:\Program Files\Vampire The Masquerade - Redemption\Maps\
