This package does not include System Shock's game data - it's
copyrighted, proprietary content that can't be redistributed. To play,
you need to own a copy of System Shock: Enhanced Edition (e.g. from
gog.com), installed (on Windows, or via Wine/Proton on Linux).

Copy its res/data/ and res/sound/ folders directly into place here,
alongside this file:
  res/data/
  res/sound/
They already contain everything needed, in the right layout - no
merging or extraction required.

Once res/data/ and res/sound/ exist next to this file, run ./run.sh from
the root of this package to play.
