Capcom will be adding more Mega Man 9 downloadable content to WiiWare, PSN and Xbox Live Marketplace this week.
US dates are WiiWare today, XBL tomorrow, and PSN on Thursday. Euro timings are unknown and may vary.
The upcoming downloadable content will be split into three packs: Hard Mode, Expert Mode, and Special Time Attack Stage.
The Hard Mode ups the difficulty a bit, the Expert mode ups the difficulty a lot, and the Special Time Attack Stage adds another level and "Fake Man" boss to Time Attack Mode.
None of the above are compatible with the Challenge Modes.
