Extract the 1.Vivi_DEU_Uncut_11.zip contents
to wherever the game is installed.
Run 2.VivisectorGoreFinal.exe
Then extract 3.VV2.rar to the game folder.
This will:
Patch to 1.1
(fixing horrible horrible sound problems)
Add a load of 'gore'
change it to 'english' text
Then play.
I noted a 'small' problem in stage one, where you're near a gate. Just
quicksave before each 'point' to be on the safe side, up to level 2 or
so, no more problems.
