Hulk smash. Roar.
In Hulk Ultimate Destruction you obviously take the roll of the big green machine. The idea is that you can destroy anything in you way to get to the objective at hand. You can take cars and split them at two and use them as metal boxing gloves, take lamp posts and use them as spears, ect. The problem is that this loses it's fun after a while. There is only one main mode in Hulk, story mode. If you want to take a break from story mode you can enter free roam which is entering a city and not going to your objective. This means you run around killing people. Like I said, this is fun, but only for a little. You will soon realize that destroying anything isn't as fun as it's made up to be. After the main story mode you will have almost nothing to do.
