Metroid Prime 3: Corruption perfectly brings the trilogy to an end
The controls of this game are it's most positive aspect. Which is quite an achievment considering the game is chock full of positive aspects. Retro Studios somehow managed to make the controls nearly as responsive as a keyboard and mouse setup. There are three control options to choose from but "advanced" is the only setting you'll need as it is the most responsive and features free-aiming lock-on. Moving around the alien worlds is more intuitive than either of the other Prime games and the action is paced to complement this fact.
The graphics are the best yet on the Wii and show that it is definitely more powerful than the Gamecube was. The artistic design is incredible and levels are filled with gorgeous detail and brilliant lighting that keeps things interesting even between the action.
The action is intense with hundreds of different enemies which have different strengths and weaknesses keeping your brain in check as well as your trigger finger. The boss battles are exciting and rewarding. Bosses are wonderfully inventive-in the same vein as the Legend of Zelda bosses. Usually defeating them involves figuring out there weak points in the heat of battle.
As in all Metroid games, Samus begins the game with minimum capabilities and discovers upgrades along the way. Upgrades unlock access to previously unreachable areas as well as making it easier to make short work of your foes.
Sound effects are extremely similar to the previous Prime games. Beams, missiles, explosions, music, and folly are all done well. The sound isn't something to write home about, except for the great soundtrack which sounds every bit as awesome as the first two games.
Overall, Prime 3 is a winner; setting the bar for all Wii shooters to come and setting it extremely high. The only way this game could have been improved is perhaps a good online multiplayer mode.
