It's too damn narrow, which makes it hard to run away, when you're in trouble. I just wish 2 people could fight on a car's hood. The areas look great. Also, the danger zones are cool. Like, how you can get hit by cars and pummelled by meat.
Outside interference is pretty cool.
Groups of people can just run in and beat everyone up for 5 seconds and leave. The moves look good. The finshers look especially good. I love te slo-mo effect. The graphics look pretty good.
