Q Entertainment may be best known for Lumines, but they also distribute free to play games like Angel Love Online too. They made a PlayStation 3 client for the game and now Guardian Heroes Online, a mobile phone RPG from 2009, is on its way to PlayStation Vita.
Screenshots from the mobile phone version.
Famitsu announced the port, which will be free to play with a microtransaction model. Guardian Heroes Online will be available for PlayStation Vita in August.
