+     "Beneath a Steel Sky is a science-fiction thriller set in a bleak
+post-apocalyptic vision of the future.  It revolves around Union City,
+where selfishness, rivalry, and corruption by its citizens seems to be
+all too common, those who can afford it live underground, away from
+the pollution and social problems which are plaguing the city.
+
+You take on the role of Robert Foster, an outcast of sorts from the
+city since a boy who was raised in a remote environment outside of
+Union City simply termed ``the gap''.  Robert's mother took him away
+from Union City as a child on their way to ``Hobart'' but the
+helicopter crashed on its way.  Unfortunately, Robert's mother died,
+but he survived and was left to be raised by a local tribe from the
+gap.
+
+Years later, Union City security drops by and abducts Robert, killing
+his tribe in the process; upon reaching the city the helicopter taking
+him there crashes with him escaping, high upon a tower block in the
