The graphics just don't look right half the time, with stiff and inexpressive character models walking around, repeating the same dialogue endlessly, in a world that looks like it forgot how to use electric light. The Invisible War™ is apparently only invisible because no one turned on the bloody light switch; otherwise, people would see you emptying a shotgun into people, plain as day. Maybe it's only invisible to you, since everyone else in the game can seemingly see in the dark.
