BioShock 2's single player game could never be as fresh and novel as the first instalment, but more than makes up for that familiarity with improved mechanics and an engaging story of its own.
The original BioShock had one of the most praised stories of any game of the last few years, with a strong narrative journey as your character explores the sunken city of Rapture, taunted over the radio by the city's creator Andrew Ryan. It had a memorable twist midway through, and provided a moment that caused you to re-evaluate your experience with the game up to that point. It also featured alternative endings based on your treatment of the Little Sisters. 4/5
