Absolutely awesome game. Its like Spiderman in that its actually fun just getting from one side of the city to the other.
"Bulletdive Drop" is the most overpowered move in the game. Its sick. When I bought it, it was unweildy to use at first, but man....take the time to use it. What I do is hang on the side of a very tall building, target something in the middle of the ruckus, run/jump like up the side of said building and at the very top, use it.
Take some getting used to the aim, but once you got it, youre a friggin beast. Creates a huge hole in the middle of the enemy, allows time and space to pick off the next big thing. Nothing can with stand it. Nothing in the game (save bosses), not hunters, not leader hunters, not anything. Pure ownage from 60 stories.
