Megaman Zero 4 ROM is the fourth installment in the Megaman Zero series. After a long journey, Ciel finally reaches her destination – Area Z. This is where Dr. Weil is said to be hiding, and where Zero makes his final stand against him. Along the way, Ciel meets new allies and revisits past ones, all while uncovering more of the truth about Zero’s dark past. The gameplay remains largely unchanged from previous entries in the series; players run, jump and shoot through side-scrolling levels filled with obstacles and enemies. However, new features have been added such as Ride Armors (mecha suits which can be ridden), double jumps, and a helpful “Chain Rod” which can grapple onto certain objects to cross gaps or swing from poles.
