Never played that one, but the train is a great way to get to 5 stars in V – cops think that since you’re not in a car, you must be a pedestrian, so they park their vehicles and get out. When they send out the helicopters, you’ll want to be on a low car ahead of a tall one so you can alternate between shooting at them and taking cover. Not dying is pretty easy; the challenge is racking up kills quickly, because you always lose all your stars in a tunnel.
