As the player accomplishes objectives, the player character is rewarded with "skill points." Skill points are used to enhance a character's abilities in eleven different areas, and were designed to provide players with a way to customize their characters;[1] a player might create a combat-focused character by increasing proficiency with pistols or rifles, while a more furtive character can be created by focusing on lock picking and computer hacking abilities. There are four different levels of proficiency in each skill, with the skill point cost increasing for each successive level.[5][6]
