A lot or a little?
Parents need to know that Contract Killer is a very gritty, first-person shooter where you are a hitman in a very realistic urban environment, making it not for kids (don't be fooled by Glu's self-rating at age 12+). Players are tasked, mission after mission, to kill people they don't know, and the game encourages players to take out their targets from an unsuspecting sniper range. Players are also encouraged to shoot their victims in the head, and there are minor blood effects throughout. Some of the other gritty elements usually associated with this genre, like drugs and sex, don't appear here, but that is mainly because the game is light on storyline. Action is the dominant factor at play, and all of the action is focused on assassinating specified targets. Parents should also know that even though the game is a free download, there are relentless pitches in the game for players to purchase items and levels with real money. Additionally, users can share high scores via the Game Center social network, but participation is strictly optional.
