Nintendo's Metroid has always been more popular in the United States and Europe than in Japan, but I'm really not sure why. The series follows the adventures of Samus, a female microbe-massacring bounty-hunter/astronaut, in some truly incredible space armor.

Samus started her career in the 1980s on the original Family Computer, but she has also appeared on Game Boy, Super Famicom and GameCube. Her latest outing, "Metroid: Zero Mission" for Game Boy Advance, takes her back to her roots.

"Zero" is a lavishly updated, strikingly reformatted and generously expanded version of the original "Metroid." The game takes place on the planet Zebes, in the same pirates' lair as the original adventure, and the basic floor plan has remained the same. You will find the same halls, doors and tunnels right where you left them 16 years ago, if you played the classic game.
