This one too:
At a basic gameplay level, the initial impression is Hulk: Ultimate Destruction meets Crackdown. This game has a similar sense of chaotic freedom and power. Rather than feeling artificially restrained, this is a game where you can run up the side of a building, then leap from rooftop to rooftop. This is a game where you can barrel down the street like a charging bull, knocking pedestrians aside and vaulting off the bonnets of any vehicles in your path. Hell, this is a game where you can jack a helicopter… while it's in the air.
While we were shown a mission from later in the game, the basic concept is that the player will be uber powerful right from the off. You will feel like a certified bad-ass the second you hit the streets of New York, capable of taking on anything. The balance, then, will come in the way the threats you face change over the course of the game.
We should also mention the simple pleasure that is jacking a tank in Prototype. Hopping onto its top, Alex rips off the hatch door before cracking his knuckles and leaping inside. A great shower of blood sprays out the hatch. Classy.
