Today Nintendo released three videos and several screenshots and pieces of artwork showcasing the Xenoblade Chronicles X's "dolls," the mecha we'll get to pilot in the game.

We get to see all the different types of dolls and their primary transformation, new artwork, and three videos focusing on the ability of the dolls to transform, doll combat and doll customization.

In the gallery you can check out in order the Formula, the Urban, the Wels, the Lailah, the Inferno, the Mastema, and the Andusias. The first three are light dolls, the Lailah and Inferno are medium dolls, while the Mastema and Andusias are heavy dolls.

Update: NeoGAF user CAAAAAAAAAAAW provided some handy translations of quite a lot of info included in today's update:

Dolls

BLADE’s Trump Card for Fighting Powerful Enemies

As you progress through the story, you will be able to take the “Doll License Certification Exam.” Upon passing, you will be able to obtain “Dolls,” indispensable weapons used to explore and fight on Mira. And once the “Flight Pack” is successfully developed, you’ll be able to use them to fly through the sky. They’re able to accomplish an enormous variety of things, so be sure to use them to explore Mira top to bottom.

Doll Types

There are three Doll types shown below, and within each type, are various models with unique characteristics.

Light Types

Low HP, high Accuracy and Evasion.

Excellent mobility in battle.

Low fuel capacity, but gets good mileage while flying.

The price makes it a good choice for beginner pilots.

Medium Types

Balanced in all areas, and easy to handle.

Excellent armor on all parts, making it difficult for them to be destroyed.

Mid-range priced Dolls recommended for pilots with battle experience.

Heavy Types

Very high HP and Defense.

Able to make frequent use of high-powered weaponry due to its high fuel capacity.

However, their heavy frames make them slow in battle, and they get poor mileage while flying.

Very pricey, but is appreciated by veterans and romantic pilots.

Doll Battle & Customization

While using Dolls in battle, they perform auto attacks with the Hand Weapons equipped to either hand, and use weapons equipped to other parts to use arts. Hand Weapons(L/R)...Rods, Swords, Assault Rifles, Shotguns, etc,

Arts

Dolls can equip up to 8 weapons to use arts

Back Weapons(L/R)...Railguns, Missiles, Grenade Launchers, etc. Use high-powered arts.

Shoulder Weapons(L/R)...Missiles, Chainguns, Laser Weapons, etc. Can use arts more powerful than Back Weapons.

Arm Weapons(L/R)...Shields, Vulcans, etc. Tend to come with arts with extra effects.

Spare Weapons(L/R)...Beam Sabers, Hand Grenades, etc. Have distinctly short Recast times.

OC Gear & Cockpit Mode

Similar to fighting on-foot, you can expend 3000 TP to activate the “OC Gear.” You do not use up fuel while in OC Gear.

When using arts, there’s a fixed chance you’ll enter “Cockpit Mode.” All arts are instantly Recast after it activates, allowing you to reuse them immediately.

Catch

You can “Catch” enemies who are suffering from “Break,” preventing them from moving for a fixed period of time. All attacks against enemies in Catch are guaranteed to hit, and the damage inflicted against them is increased, so make every effort to use it in battle.

Doll Fuel

Dolls use up fuel while flying around, and when using arts in battle. Fuel recovers slowly when you disembark from the Doll, but you can also refuel them at NLA.

Doll Customization

You can use the console at the BLADE Home to change your Doll’s equipment, name, coloring and so on.
