(GBA) Rockman Zero 4

The last episode in the series is centered on the struggle between Neo Arcadia, now dictatorially led by Dr.Weil, and Area Zero, populated by humans escaped from Neo Arcadia.
Zero in this episode can use the “Z-Knuckle” which allows him to perform special actions like hanging from pipes or destroying obstacles; the “Weather System” allows the player to choose two weather conditions, for example the snow covers spikes and Zero can pass over them without taking damage : with “hard” weather some secret passages become reachable while the “easy” weather doesn’t reward the player with the Ex Skills.
It was introduced also a Easy Mode (but weather cannot be changed) and as usual several mini-games are unlockable upon reaching certain conditions.
