Mega Man Zero 4/Chips & Sub-Tanks

In previous Mega Man Zero games there was a limited number of chips (usually three), and they were collected upon defeating specific bosses. In Mega Man Zero 4, instead, every enemy (except for bosses) occasionally drops a Part with the same name; combining different parts, you can obtain Chips. There's a total of 27 chips.

In order to combine Parts to obtain Chips, Zero should talk to Cerveau, the scientist reploid in the Resistance trailer. Many characters in the Resistance trailer and in the human settlement will give clues to combine parts or even full recipes for chips. The S-Crystal and the Junk part can be obtained from recipes as well.

In this page, if a part can be found in the Second Introduction Stage, no other location is listed: the player can simply re-visit the 2nd Intro Stage to collect it. Furthermore, locations that cannot be revisited are not listed, with two specific exceptions:
 * The Moloid part can only be found in the non-revisitable First Intermission Stage; make sure you collect some before clearing it!
 * The CryoNeon and NeedBalloon parts can be found only in a non-revisitable portion of Tech Kraken stage or in the final stages.

There are four Sub-Tanks in the game. See the section.

In the Japanese version, Ceratanium was actually Ceramic Titanium. See the section for its location.

Head Chips
Talk to Tornado after the introduction missions to get the recipe.
 * Q-Charge1

This chip allows to charge Zero's weapons faster.

Talk to a Caravaner after the intermissions to get the recipe.
 * A-Recover1

This chip allows to restore HP if Zero stands still.

Talk to a Caravaner after the intermissions to get the recipe.
 * WeaponPlus

This chip adds one ammo to the special enemy weapons that have a limited number of shots. It has to be equipped before getting the weapon.

Body Chips
Talk to Faucon after the introduction missions to get the recipe.
 * Absorber

This chip prevents Zero from getting knocked back when hit. Its effect is actually identical to the "Buffalo"-type animal Cyber-Elves from the previous three Mega Man Zero games.


 * Reflect
 * Cyber-Elf lv.4: "Ceratatium + propeller + reflective beam parts = new chip."

This chip allows to reflect enemy bullets with a Saber slash. Its effect is the same as the Shield Boomerang (used as a shield) from the previous Mega Man Zero games.


 * Strong
 * Hirondelle: "In order to make body chips, you'll need to pick up Ceratanium."
 * Cyber-Elf lv.5: "With hard mechaniloid parts you can strenghten your body."

This chip allows Zero to survive when he touches deadly spikes, although he gets a lot of damage. Its effect is the same as the 3-Levels animal Cyber-Elves from Mega Man Zero 2 & 3.


 * Rolling
 * Cyber-Elf lv.6: "Hammer + flame thrower + spinner + Ceratanium = new chip."

This chip allows to make spinning slash jumps and spinning slash dashes. Jump, press Up and slash for a spin jump; Dash, press Up or Down then slash for a spinning dash. These two effects were available in all the previous Mega Man Zero games, but always from a different item (upgraded Saber in MMZ1, a Form in MMZ2, a hacker Cyber-Elf in MMZ3).

Foot Chips
Talk to Brise after the introduction missions to get the recipe.
 * SpikeTypeW

This chip allows Zero to walk normally even when he's in a magnetic field or in strong wind.

Talk to Tiphon after the introduction missions to get the recipe.
 * Quick

This chip allows Zero to run faster. Its effect is the same as the lv.1 animal trait of the Cyber-Elf, but it does not stack. In previous Mega Man Zero games, the same effect was obtained from an animal Cyber-Elf.


 * Frog
 * Cyber-Elf lv.3: "Use magnet enemy and frog enemy parts for a new chip."

This chip allows Zero to slide down walls more slowly. Its effect is the same as the lv.2 animal trait of the Cyber-Elf, but it's not stacked. In previous Mega Man Zero games, the same effect was obtained from an animal Cyber-Elf.

Secret Chips
Clues from Cerveau:
 * - "An easy way to make chips is to find recipes, but better chips don't have recipes."
 * - "Try just combining some of the parts you have. You might discover a brand-new chip."
 * - "Some chips have different levels. Just add a certain something to a level 1 chip and it becomes a level 2 chip."

Head Chips
These chips are upgrades of Q-Charge1. They work faster.
 * Q-Charge2 & Q-Charge3

These chips are upgrades of A-Recover1. They work faster.
 * A-Recover2 & A-Recover3

This chip allows to charge weapons automatically, with no need to hold down the button.
 * A-Charge

This chip slowly refills special enemy weapons that have a limited number of ammo.
 * A-Filling

Body Chips
These chips are upgrades of Strong. They further reduce damage from deadly spikes.
 * Stronger & Strongest

This chip extends the invulnerability time after Zero gets hit. The parts come from the three different enemies emitted by Mechamesons.
 * Extend

This chip allows to destroy enemy bullets with a saber slash. In previous Mega Man Zero games, the same ability could be obtained from a Form (MMZ2) or a hacker Cyber-Elf (MMZ3).
 * Erase

This chips reduces by 1 the score penalty for using the Cyber-Elf at a level higher than his capacity. Nevertheless, score and rank have no real effect in the game.
 * Elf

Foot Chips
This chip allows Zero to perform a second jump in mid-air. It is extremely useful, and it comes in handy countless times during the game.
 * DoubleJump

This chip allows Zero to jump on the surface of water. Its usefulness is limited: it can only be used in the second final stage of the game and in a non-revisitable portion of an intermission stage.
 * SplashJump

This chip prevents Zero from sliding on ice surfaces. Its usefulness is limited: it can be effectively used only in the Teleport System in the last stage, in the two battles against ice-elemental Einherjar; it can also be used in an optional portion of Fenri Lunaedge's stage.
 * SpikeTypeI

The Galacta Armor
Galacta is Japanese for Junk. If Zero wears all three Junk chips at the same time and also is not using the Cyber-Elf (i.e. all traits set to zero), damage dealt and received by Zero is doubled. This effect corresponds to the Hard Mode in Mega Man Zero 2.

If you complete the game without feeding any E-Crystal to the Cyber-Elf, a mini-game is unlocked. This requirement matches the requirement to use the Galacta Armor.


 * JunkHead

(The recipe looks like an upgrade of the Strong chip.)
 * JunkBody


 * JunkFoot

Special parts & Sub-Tanks

 * S-Crystals & Sub-Tanks
 * Tiphon: "You can make an S-Crystal with Ceratanium and some enemy parts. The recipe requires one type of Variant, some robot that spits out other robots and then something with an orange body."
 * Faucon: "If you can find an S-Crystal, Hirondelle might trade you one Sub-tank."

An S-Crystal is also used for one chip of the Galacta Armor (see below). Two more Sub-Tanks can be found for free in the stages of Noble Mandrago and Fenri Lunaedge, respectively.

Mix any two, three or four parts (you can also include more junk) that are not compatible, and you will get a junk part. If you're lucky, you can guess one of the Secret Chips: this will be added to Cerveau's recipes list, so don't worry about remembering it.
 * Junk

The Ceratanium (or Ceramic Titanium) is the only part that can be found lying in stages.
