Players are further encouraged to customize their characters through nano-augmentations—cybernetic devices that grant characters superhuman powers. While the game contains eighteen different nano-augmentations, the player can install a maximum of nine, as each must be used on a certain part of the body: one in the arms, legs, eyes, and head; two underneath the skin; and three in the torso.[7] This forces the player to choose carefully between the benefits offered by each augmentation. For example, the arm augmentation requires the player to decide between boosting their character's skill in hand-to-hand combat or his ability to lift heavy objects.
