During a press conference this morning Sony Computer Entertainment Japan and Square Enix revealed a Dragon Quest spin-off for PlayStation 4 called Dragon Quest Heroes. This game comes from a collaboration between Dynasty Warrior's Omega Force (that it's developing the game), Square Enix and Koei Tecmo.
Dragon Quest Heroes will launch in Japan in Spring 2015 (alongside a special PS4 version, the Metal Slime edition), but no western release has been announced yet. Check the announcement trailer below!
