Parents need to know that Counter-Strike: Global Offensive is a free-to-play competitive, team-based first-person shooter available for download on Windows, Mac OS, and Linux-based computers. Players are split into teams of either terrorists or counter-terrorists, competing online in a number of scenarios including keeping or rescuing hostages and setting or disarming bombs. Violence is a staple of matches, with players using a variety of realistic weapons, such as guns and knives, to eliminate the opposing team. While there's some blood and realistic violence, it’s not overly graphic. Parents should be aware that, as a competitive online game, there's a heavy reliance on online communication, which can expose kids to toxic behavior, offensive comments, and profanity from other players.
