One of them is collection mode, which adds data you found to a Mega Man Zero mini-museum. Part cards, character cards, and wallpaper illustrations can be viewed in this mode. Collected character cards for heroes, rivals, and even rare characters come with information about them. A glimpse of this mode was revealed with the debut trailer.
Retailer Game Star also mentions easy scenario mode, a mode that lets players experience the whole Mega Man Zero arc in sequential order. However, it’s unclear if or how this will be different from just playing games on a Game Boy Advance in order.
Mega Man Zero Collection arrives in Japan on April 22 and has a floating summer release in North America.
