Konami's flagship frog continues its hopping and dodging ways in Frogger: Helmet Chaos on PSP. As in the 1981 arcade game, which is included as a bonus, the action involves frantically moving from point A to point B while avoiding an assortment of obstacles. Modern updates rework the classic formula to include multidirectional movement across 3D environments. The story involves Frogger saving his beloved FireFly Swamp from an evil alligator named Dr. Wani. Players will explore 30 top-down levels while mastering new techniques such as the double jump and tongue grab. Up to four players can compete in special mini-games using the PSP's WiFi network mode.
