Mega Man Legends 2 will be accessible on Apr 5th from the PlayStation Network.
The proclamation came from a PlayStation Blogcast (via GameInformer). Presumably Mega Man Legends 2 will be accessible for PlayStation 3 and PS Vita, like a other PSOne Classic titles accessible on PSN.
Mega Man Legends 2 creatively expelled in 2000 and is a three-dimensional take on a Mega Man. Instead of battling drudge masters, however, you’re exploring dungeons looking for epic rob while we try to expose a gigantic energy source, a Mother Lode.
