  7. ACHIEVEMENT INFORMATION [c07]
===============================================================================

BioShock has a total of 50 achievements, allowing you to earn a total of 1000
GP (gamerpoints). This section lists all of the achievements, how many GP they
are worth, and how to get them. Unless otherwise noted, all of the achievements
require everything to be accomplished in one playthrough (i.e., if you obtain
half the audio-diaries, restart, and then obtain the other half of the diaries,
you won't get the historian achievement, etc.) This section has some major
