Probably the best action game available for the Wii.
The story centers around a dude named Travis Touchdown, who is a stereotypical otaku living in a place called Santa Destroy. After Travis wins a beam katana in an internet auction he becomes an assassin. When he runs out of money to buy video games and wrestling videos, he accepts a job to kill an assasin called ''Helter Skelter'' and succesfully kills him. This earns him the 11th rank in the United Assassins. Realizing that he is now marked as a target for assassins, he sets out to secure himself the position of ''Number 1'' assassin in the UAA.
The good:
Exciting boss fights, sharp controls, lots of action, good story and humor.
The bad:
Side missions are rather short.
Gameplay:
The combat is the part where it shines. You control Travis. Armed with a Beam Katana(which you can upgrade to MK-II/MK-III and make it stronger) You must battle your way through a lot of goons, ranked assassins etc. You don't have to swing your wii-mote to slash, instead you use the A button to slash and the B button to punch to make your enemy dizzy and to kick. When your enemy is almost dead or you win a dead-lock you must use a ''death blow'', which, as the name suggests kills your opponent(except for bosses) and you have to swing to the direction(left,right,up,down). After you do a death blow, a slot machine spins at the bottom of the screen and if a triple match occurs, you enter one of the 4-5 Dark Side modes. In one Dark side mode you have to press on a different button to kill your opponents, and in one dark side mode you are able to shoot some kind of energy balls with your beam katana. Each power up are awesome to watch as well as to do. When your opponent is in a dizzy state, you can use a wrestling move, which also requires movement with the wii-mote. You learn a wrestling move before each boss fight or by purchasing a video at a store named ''Beef Head''. Slashing your opponent to bits, cutting them in half and using wrestling moves on them, never gets old and it is so much fun to do. Unless you buy the expensive energy saving III, every Katana has batteries, which goes empty after repeated use. When it's empty, you must hold the 1 button while going up and down rapidly with the wii-mote to recharge it. Before you go into a rank battle, you must earn money to pay the entrance fee. How do we do that? Simple! We do side jobs and assassination missions. There's a variety of jobs and assassination missions that are fun to do. Even though working for money sounds boring, it definitely isn't in this game, especially assassination missions. Slashing enemy up for money? How cool is that! You get to bash your enemy's up and get money for it. Nice, huh? You can also customize the clothes of Travis, you can buy new clothes at a shop called ''Area 51''(sounds familiar...), there's a wide selection of jackets, jeans, belts, you name it. There are also mini games you can do when your tired of all the missions and stuff.
Graphics:
This game has terrific graphics. The visual design is full with strong color choices, cell shading and good done shadows. The designs of the Schpeltiger, the clothes you can buy and the bosses are awesomely done. The minimap and health indicator are pixelated by design and the menu resembles 8-bits. The enemy cut in half and the blood etc is also well done.
Sounds:
The game provides great sound effects and sounds overall. The voice acting is well-done and they resemble their character well, such as Sylvia's french accent and Travis' bloodthirstiness. The boss battle musics are also great, they give you the feeling that your in a heated battle and it powers you up and gives you the urge to beat the boss.
My opinion:
Aside of the around 15 hours of gameplay(I myself finished it on 14 hours), it is a very solid action game and it is the mature action game you should get. I myself had a lot of fun playing this game from the beginning to the end and I am sure you will, too. So i'd say: Buy the game, it's definitely worth it, trust me!
