Developed and published by Alvion, Malicious Rebirth is portable version of the downloadable 2010 PS3-exclusive.
Released in Japan for the PlayStation Vita, Rebirth features additional content in the form of new enemies and a bonus chapter for players to explore. However, only now are we getting solid details of a Western release after the following Tweet:
@splashdowntiger The other day we trusted an English localization to a English publisher, so it depends on them. We will rush them again.

Sony Entertainment America/Europe previously handled the localisation of Malicious on PlayStation 3. Whether or not a similar arrangement has been found for Rebirth has yet to be confirmed.
