The pinnacle of technology and game play for the Wii resides within this game.
Metroid Prime 3: Corruption (being the end of a trilogy or something, still expect more Metroids though) is a fantastic game, and as the title suggests, there is corruption in the plot. Heres a summary; Samus is fighting space pirates, gets infected with phazon which is uber powerful, space pirates planning something, Samus gets mad, fighting ensues. No point in ruining the plot for you.
The phazon plays a pretty big role in game play, as when it is initiated Samus gains unbelievable power and can demolish everything in sight within seconds (bosses not included, and many other things actually). You need to activate the phazon at certain points as part of the whole puzzleish aspect of Metroid, and as an attempt to keep some things fresh for a new game. Nothing is new.
You got your other bounty hunter friends roaming the galaxy too, but for some reason, they all just leave you in the dust and then you have to beat them up. I won't say why, but there is a little gap in the plot as to why Samus is alone on this mission. I also must complain about something on the whole series itself, shooting doors to open them. I get it, they act as load screens (you can tell when they don't open right away, and you think its frozen or something but its actually loading) however, when in a federation ship you have to shoot open their doors, but when you shoot the people on board they have these awesome shields on them that are not mentioned or used in the game anywhere else. It makes no sense.
All that being said, for the Wii, this game looks amazing. Highly detailed environments with rich detail to the atmosphere. The animations are fluid most of the time (some pirates could have used polishing) and the graphics maintain a nice consistency. In fact it is safe to say that this is the best looking Metroid game ever. The developers made this from the ground up for the Wii, and their labor shows.
The controls on the Wii and I are in conflict. Many games fail for me because they can't grasp the controls well enough and so I've grown to resent motion controls. Metroid does a nice job of minimizing these motion controls. Point the remote to aim, and sometimes swing the nun-chuck to activate your energy whip. There are some neat switches that require twisting and pulling, but because they are not in an intense situation there is no pressure to get them right away. In most cases they are also fun.
The puzzles in the game are really finding your way through the rather linear environments. Because you may need to find a crack to get through a hidden hallway to get a device to open a door and back track it does create a sense of linearity. This is not bad as the level design is great, and there is action to keep you awake. While a nice physical attack would have been appreciated for when you get close and personal with the aliens, the shooting is good. Although it lacks, because aiming is really easy with the remote and you need to fire like a thousand times to kill anything to make up for the ease.
What I like is the devices you get, like the grapple, ice missiles and even upgrades for your ship which become crucial for the game. Like when you get missiles for your ship, you get to activate them plenty of times.
The sound is great, music is wonderful and accents the atmosphere and there is full voice acting (except for Samus, she doesn't talk) which actually is not bad.
You got a Wii to play games, and this delivers in a sea of terrible titles. A must buy as it has a great atmosphere of puzzle and action game play.
