The project has been cut.
The toughest battles are in the cities, because there isn't a good point of view to navigate. It seems like F1 is the view that's most practical as it offers the broadest view. F2 is too cramped, I forgone this at the expense of the cockpit feel. F3 is where you can see yourself in 3rd person from the rear, helpful at times but since the helo is in the middle, it obstructs your view. I'd have to give it a hard difficulty even if you're playing on Easy mode, because you can't save while you are on a mission - you either finish it successfully or you'll have to retry it until you do, which can be frustrating. For example, when you're 99% done with a mission while you're on low health, brushing against a tree with your rotors could be disasterous.
I didn't check out the multiplayer because think about it. Everyone will be flying a Comanche trying to down the other guy with a Stinger. Even if the enemy dodges a Stinger, what's the prevent him from escaping a salvo of them? So it's whoever spots who first that wins, not much variety there.
This isn't a complicated helicopter sim, it is fairly easy to get up and running in this game. It can be tweaked for a more realistic feel. It feels like a mix between a sim and an arcade, so if you're tired of overcomplicated aircraft sims then this could be the answer you've been looking for.
