Alvion announced a PlayStation Vita port of PS3's Malicious months ago but went silent following the announcement. Thanks to this week's Dengeki PlayStation, we at last have some details.
The Vita port has been renamed "Malicious Rebirth." It's not exactly a port, though. Alvion is adding lots of volume to the game, with new stages and new actions.
A release is planned for the summer, so we should be getting more details shortly.
