This was the 3rd installment in the series and by a lot of people considered to be the best. It's a fun Hack n Slay game, with a lot of humor and probably one of the best games of it's kind.
The game starts out by telling you the story of the legendary Dark Knight Sparda, who sealed the devils in their realm and later on had two sons. You play as one of those sons, whose name is Dante. His twin-brother Vergil let a tower appear, that is a Link between the humand and the devil realm. Dante now goes on an adventure to stop his brothers madeness and kick some ♥♥♥.
It's an easy to learn, but hard to master type of game. The camera can get a bit of annoying while platforming, but after a while, you get used to it. The fighting itself has probably the best system I've ever seen in these kinds of games. You can link so many combos together, do awesome stunts, etc, that you'll never be bored. The game is a bit hard for newcomers, but it's rather forgiving and gives you a lot of variety to play in your own style.
For it's time, the graphics were rather good. Sure, there are opticaly more refined games, but this one looks not bad.
Atmosphere and Unlockables +3 points:
The atmosphere is very well done. You always have this kind of devasted-dead looking scenery around you, mixed with kickass music, that will make you enjoy it a lot.
Also, you can unlock a lot of Demon Arms(Weapons) and Guns, as well as 2 new styles, which makes it a total of 6 styles. You can also get some costumes, every time you play through a difficulty. If you beat the game at least once, you unlock a new type of "New Game", where you can play the game as Vergil and the Bloody Palace. There you can show how good you have become and fight through hordes of monsters.
It's probably the best game of it's kind, packed with a lot of humor and great moments. You are running around as this white haired badass, who can always make jokes, no matter how serious it gets. If you like these kinds of games, you'll definitly enjoy it.
