Character designs from Bioshock 2, which primarily include a range of mutated and misshapen civilians and intimidating, faceless beings bound to the armor and weapons they wear. For the civilians, imagery of various injuries from World War 1 and 2 were used to create disturbing mutations and ugly marks over their bodies. The setting and fashion design also seems to stem from the same time period, adding to the lauded and effective atmosphere of the game. As the game is in first person it offers more focus on these kind of design features as well as a more restricted field of vision, enabling the player to easily be taken by surprise. These two aspects of the game contribute to gameplay with a strong and successful sense of tension. The main threat in the game, however, are the more than conspicious are the 'Big Daddies/Sisters' adorned in detailed and heavy armour developed from the atmospheric diving suits used to travel into deep water. Like the mutants, these enemies are paired with another aspect of the game for added effect - The world is set in a built civilisation underwater, making these enemies both impervious to the main danger to your character and able to follow you no matter where you go. These kind of effective character and and environmental concepts provide a lot to more than just a few key traits of any game.
