This package does not include System Shock's game data - it's
copyrighted, proprietary content that can't be redistributed. To play,
you need a copy of System Shock: Enhanced Edition (e.g. from gog.com).

From your Enhanced Edition install, you need its classic-game data and
sound files - the res/pc/hd/data and res/pc/cdrom/data trees merged
together (res/pc/hd's copies win the couple of filenames present in
both: intro.res, objprop.dat), and the res/pc/hd/sound tree, packed
inside the install's sshock.kpf (a zip file).

Copy that merged data into place, alongside this file:
  res/data/   <- res/pc/hd/data + res/pc/cdrom/data, merged
  res/sound/  <- res/pc/hd/sound

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