Alex Kidd leaps from Sega Master System to Genesis for his first and only 16-bit adventure. It seems the young hero's father has gone missing somewhere on Paperock Planet, and it's up to players to help find him. The platform-style action has little Alex exploring a number of vibrant locales and defeating such enemies as mummies, baboons, and scorpions throughout 11 levels of play. Alex can perform a combination of jump kicks and punches to defeat his foes, while he searches for chests filled with helpful items. Each stage also features some rather unusual boss encounters, which involve playing games of "rock-paper-scissors" instead of more traditional battles. A victory earns players money used to purchase one of seven offbeat gadgets, from a pogo stick to a wizard's cane.
