New Super Mario Bros. revitalized the classic side-scrolling action for a new generation on the Nintendo DS. Combining 2D backgrounds with 3D character models, it offers a visually striking 2.5D aesthetic. Players control Mario or Luigi through 80 levels across 8 worlds, battling the Koopalings to rescue Princess Peach. The game introduces game-changing power-ups like the Mega Mushroom (turning Mario into a giant), the Mini Mushroom (shrinking him to fit through tiny gaps), and the Blue Shell. New moves like the wall jump and ground pound add depth to the platforming. With hidden Star Coins in every level and a suite of multiplayer modes, it became one of the best-selling DS games of all time. This official iQue version provides a high-quality Simplified Chinese experience for the Chinese market.
