Urban Chaos shows us how perfect the "old" games can be, humiliating today's games of the same style.
D'arci is the main character. Her attitudes are a crucial element to justify the good rating of this game. The dialogues are quite exciting, and D'arci's skills are impressive.
The plot is very traditional, however well-articulated. Taking the position of a big city's hero is very fun, screaming "Stop, Police!" to the passerby (more usually to criminals), running by the streets, etc.
Union City is one of the bests game-cities I've ever seen, with typical chaotic city environment, New York style (who does not loves New York?), dark alleys and leaves and cans all over the walkways, floating around when you pass by. Also, the possibility to not just explore the streets, but the buildings' roofs, is revolutionary.
Although the game is pretty hard, and some levels can be very painful, it is definitely something that is worth looking for to buy.
