Mega Man Zero Collection is set to hit the Nintendo DS on June 8 here in North America. The collection will retail for $29.99 and will include all four of the Mega Man Zero games that were released for the Game Boy Advance. You can expect some new features as well such as an easy mode to be included in this re-release.
For more on the game, check out the official Mega Man Zero Collection website which just launched today. The press release for this announcement also says to check out this post on Capcom-Unity for more details, but it's the same exact info on the blog that's in the press release. Capcom's PR tricked me. Jerks.
