Ghost in the Shell is about the horrors of technology.
Ghost in the Shell Stand Alone Complex is about using a computer to shoot people for fun in a deathmatch setting pretty much cloning the Call of Duty/Half Life Engine. It’s basically an e-Sport with decoration.
It looks pretty and has a lot of production value including Richard Epcar’s voice as Batou! However, it’s not any different of a game we haven’t seen the last 10 years. It lacks a compelling story that Ghost in the Shell had and is really a milking of that franchise, having nothing to do with the fears of technology and actually is technology we should fear, using machines to weaponize humans.
