Capcom's Mega Man Star Force 3 for DS is set to launch next Tuesday, June 30, and the publisher has released a playable demo on the Nintendo Channel.  If you're interestedt, better check it out soon because the demo will only be up for a limited time.

Additionally, we have a gameplay clip from the "Red Joker" version, one of Mega Man's available forms in the new "Noise Change" system, offering our protagonist random enhancements.  The other version is "Black Ace," which we have yet to see.
