"The paramedics report that they were unable to find his eyes. We think he may have eaten them."
Korsakovia is a HalfLife 2 mod, and as such you must have a pre-existing
installation of HalfLife 2 to play this title -- I tested this mod against
HalfLife2/The Orange Box installed via Steam.
This mod does not come with an installer - to install this mod, simply
download the Korsakovia .zip file, and unpack it's contents into the
following location (linux path shown);
~/.cxgames/[bottle_name]/drive_c/Program Files/Steam/steamapps/SourceMods
When you restart Steam, the mod will show up in your list
of games - play the mod...be afraid, be very afraid..
Cheers!
