Mario may be Nintendo's standard-bearer, but Samus Aran of the "Metroid" games is getting her own chance to headline. And it's the first new story in the series in 19 years to play in 2D, picking up after "Metroid Fusion," released in 2002 for the Game Boy Advance handheld. "Metroid Dread" pays homage to that game with its side-scrolling heritage that goes back to the first installment in the series, "Metroid," from 1986. Samus moves fast and fluidly runs, jumps, slides and climbs through lush landscapes with detailed 2.5D backgrounds. A new power, the Spider Magnet, allows the character to climb walls and stick to ceilings like Spider-Man.
