Zero Collection Page Gets Some Action

After blowing so many minds last week with its story and timeline synopsis, the Rockman Zero Collection homepage has been updated this week with some less jaw-dropping but still cool info nonetheless. The Action section has been updated, which demonstrates Zero's weapons throughout the series. These include his Z Sword, Buster Shot, Shield Boomerang, Triple Rod, Chain Rod, Recoil Rod and Z Knuckle. Each weapon has illustrative videos which show how the weapons are used. Something that I find curious is that the videos have no music at all. Is it perhaps an indication that they're updating the soundtrack?
