Mega Man Zero 4/Walkthrough

Introduction
Even though Omega has been defeated and the world is safe from the Dark Elf, the human utopia known as Neo Arcadia has fallen under the rule of Dr. Weil, turning the once-peaceful city into a wasteland. At the start of the game, we find a moving trailer of humans fleeing from Neo Arcadia. With Weil's soldiers known as Variants chasing after them, Zero attempts to guide the trailer to safety.

Main Characters
Zero: A Reploid that has been hibernating in a lab for well over a century. He has been ressurected by Ciel, a human scientist to save the world.

Ciel: A human scientist and leader of the Resistance Base, a refuge for Reploids suspected of being Mavericks.

Dr. Weil: A human banished from Neo Arcadia for a century for starting the Elf Wars.

Craft: A combat Reploid who shares close feelings for Neige.

Neige: A human journalist and leader of the Caravan, a human's refuge from Neo Arcadia. She is also Craft's friend

Changes from the previous game
Let me a welcome a new weapon obtained from the start of the game. Here's what it does:
 * All weapons are given to you from the start.
 * To get chips, you must synthesize them from fallen enemy parts.
 * There is only one Cyber-Elf in this game. However, it exhibits Nurse, Animal, and Hacker traits and must be fed with E-Crystals to level up and learn more skills. For every level you use up, it becomes the Elf Level. Do not exceed the Max Level in a mission, or you'll lose points.
 * All 8 main missions are availailable from the start.
 * No elements are available, instead using EX Skills as elemental attacks.

Zero Knuckle: Intro Mission:
 * A hand weapon with a grabbing attack.
 * Use it on enemies to steal their weapons. The amount of times you can attack range from one to infinity.
 * Yank out objects.
 * A very useful tool in boss battes. For example, when Noble Mandrago's head pops out of the ground, you can yank her out using the Zero Knuckle.

Destroy the Variants as you start right. Do not touch that road, or you'll take big damage. You can steal the Variant's fire attack to burn away the exterior of some of the trains, revealing E-Crystals and extra lives.
