While the helmet lacks any sort of expressive features, a head tilt is more than enough to let you know what she's thinking, and it's probably nothing good as she is always trying to kill you. The rest of the helmet is composed of pieces of metal taken from suits of fallen Big Daddies that were welded together to protect her noggin. The glaring red light emanating from the portal is the focal point of Big Sister's design that was intended to intimidate the player in dark areas.

The Big Sister helmet is a departure from the helmets of the Bouncers and Rosies you encountered in the original BioShock, and is much smaller and rounder, almost making her look like an insect. In this design breakdown, we take a look at some of the nuances in Big Sister's design to gain more insight on this character that you'll become very familiar with once BioShock 2 hits stores next week. While we don't know what lies underneath the diving suit of this Big Daddy/Little Sister hybrid, we can examine her design and hazard a few guesses. Big Sisters are the new kids on the Rapture block who you'll encounter quite a bit in the sequel.

In our coverage of BioShock 2 over the past few months, we've provided details on the changes you'll encounter during your next excursion through Rapture, put a name to the mysterious Big Daddy protagonist, Subject Delta, and uncovered details on new and familiar faces in the game.
