If you expected Metroid Prime 3: Corruption to be a high-quality continuation of the series, you'd be right. And yes, the Wii controls are terrific and intuitive, so if you hoped that controlling bounty hunter Samus Aran would be a dream, that wish has been granted, too. All told, even though Corruption's easier battles and conservative design sometimes seems like less of a sprawling Metroid adventure and more of a straightforward first-person shooter, it's still a great action game that does exactly what you expect it to do, no more and no less.
Of course, the five years that have elapsed between the original Metroid Prime and the trilogy's final hurrah is an eternity in gaming, so even with its smooth, Wii-specific controls, there is a strong sense of familiarity here. While Metroid Prime spectacularly ushered Metroid gameplay into a 3D vision, Corruption is content to be a solid successor. Yet you shouldn't let some spurts of predictability dissuade you from checking it out, particularly if you are a Metroid enthusiast. Corruption offers its own formula tweaks while staying true to its roots, and like the previous games in the Prime series, it sends you on an atmospheric journey of discovery and enjoyable boss fights.
The exotic worlds of Corruption will excite series fans, and for good reason. Like its predecessors, Corruption features superb art direction, so every level is even more incredible to explore than the last. While it isn't a huge step over Metroid Prime 2 in terms of sheer graphical quality, there are plenty of elements that will catch your eye, such as Samus' visor reflections, or the detailed, complex machinery that brings some of the environmental puzzles to brilliant life. The biggest surprise in the production values is the addition of a good deal of voice acting, at least toward the beginning of the game. You'll still spend most of your time exploring in relative silence, and the eerie, great soundtrack keeps you in just the right mood. But occasionally you'll interact with bounty hunters and other characters, and their lines are mostly spoken. The voice acting is fine, though its presence does reinforce just how effective the ghostly silence was in the first two Prime games.
If you're a Metroid fan, there's no need to convince you to play Metroid Prime 3: Corruption. It's got exactly what you would expect from the last in an acclaimed trilogy of titles: great boss battles, involved environmental puzzles, and a smooth control scheme that cements exactly how FPS controls should work on the platform. It'll also keep you busy for a while, since you can earn tokens for completing various tasks and use them to purchase unlockable goodies like concept art and bumper stickers for Samus' ship. While the lack of multiplayer is disappointing, the single-player campaign won't leave you wanting. In the end, you may not be able to shake the feeling that you've done all this before, but it will still make you grateful for how great it is at its core.
