For many players,BioShock 2was a dream sequel returning to the underwater city of Rapture. Playing through the eyes of a Big Daddy, Subject Delta, the 2010 title retains much of what made the originalBioShockso beloved by fans including a first-person shooter perspective and expanding on thestory surrounding Rapture’s downfall. And much like the first game, Subject Delta will be able to upgrade his weapons throughout the course of the story.
While once again exploring Rapture, players must use weapons to dispatch splicers and other enemies. This time around, there are 14 upgrade stations which can vastly improve the effectiveness of each weapon. Used with theDNA-changing abilities of plasmids, Subject Delta can break through whatever obstacles block his path during the plot. However, the six weapons now have three upgrades each so players must choose which of Subject Delta’s weapons to max while leaving the others at a lower power level. Furthermore, if early upgrade stations aren’t used, Subject Delta will be unable to backtrack to them later so this guide will cover all locations.
