Duck, you sucker.
Okay, let's get this over with. It's kind of hard to review a game like this in 100 words, so let's just cut to the chase so we can get to what everyone really wants to hear. So, Duck Hunt: you shoot ducks. The end.
Now that that's out of the way, let's talk about that dog. Is there anyone out there who HASN'T fantasized about unloading an entire clip of armor-piercing bullets into that smug little face of his? They should make a sequel called Duck Hunt 2: Doggie Season, where you're chasing that little bastard through a field of high grass, armed with two rifles, a machine gun, a Walther pistol, a sawed-off shotgun, a couple of grenades, and a rocket launcher. And unlimited ammo for all of them. Cathartic wouldn't even be a strong enough word.
