The Warriors (PS2)
Plenty of movies also have video game adaptations, though that usually happens with movies that are still in cinema's at the time of the games release, the game came out in 2005 and the movie, 1979. I haven't seen the movie but the story in the game follows a gang called the Warriors, who have been falsely accused of murdering a high ranking gangster and must fight their way back home defending themselves against the gangs of New York. Well that's the story the back of the box says it had, but it doesn't take place until the last 4 levels of the game, before that you must do standard gang stuff, steal car radios, rob shops, mug people, throw other gangs under trains, throw a Molotov at a prostitute etc. The game is a brawler and you'll be controlling one member of the gang whilst giving orders to the others, this leads to mass brawls against the gangs of New York who range from a bunch of mimes to skinheads. The game is very fun, the controls are easy and the music is intense. One thing you can do is steal other peoples hats, and if you can manage to not get it knocked off, the gang member will still have it on in later cutscenes and levels.
There were 1 minor problem and 1 less minor problem and 1 really annoying problem. The minor problem I had with it, was the credits lists all the graffiti artists they hired for the game to help make New York realistic, but The Warriors have the worst tag in the entire game (It's literally a red W), the tagging mechanic is also frustrating. The bigger problem was that friendly fire is on, and about ¼ of the people you hit will be your own brothers, and to make it more annoying your gang will do stupid things like charge and dive into you, knocking you over, as well as throwing molotovs on enemies who are standing next to them, setting themselves on fire. The really annoying part was you use stealth during three levels in the game, the first level, and 2 of the last three levels. I found it annoying that they expect you to remember how to do a stealth kill after going through about 15 levels of no stealth.
But those are just little niggles, the game is incredibly fun and I would recommend getting it. It's also available on Xbox I believe.
