Fantastic! One the games in my library with the most replay value for me.
Lots of side missions available, and lots of fun random crimes to stop. And just swinging through the city, performing acrobatics, picking up speed, running on walls, is fun enough!
I found some fights challenging, but do-able. Upgradable speed, fighting moves, and more are available. Large city to explore and defend.
I would recommend this game to anyone looking for some fun action (with a warning to those that get motion sickness easily).
