Japan is getting yet another custom PlayStation 4. Sony has announced a special "Metal Slime" console for Japan, which is being released to mark the launch of Dragon Quest Heroes, an upcoming hack-and-slash action role-playing game in the style of Dynasty Warriors.

　　The smiling slime blob featured on the PS4 itself is a removable USB cover, not a permanent fixture, Joystiq reports. Sony has not said when the Metal Slime PS4 will be available in Japan (Dragon Quest Heroes itself is launching sometime in 2015) or what it will cost. It's also unclear if the special system will ever makes its way to the United States or Europe.

　　Sony announced the new PS4 model during a special press conference yesterday. This event also provided confirmation that Persona 5 is coming to PS4, a launch date for Bloodborne in Japan, and news that the PS4 and PlayStation Vita are finally getting theme support. Capcom's Resident Evil: Revelations 2 was also officially confirmed during the show.

　　The Metal Slime PS4 is not the first custom console revealed for Japan. Following the massive success of Disney's Frozen, Sony announced a limited-edition system based on the movie with laser-engravings of the movie's heroes, Elsa and Anna.

　　The only PS4 available in the United States and Europe right now is the standard black model. However, this will change next week when Sony launches a $450 white console with Bungie's new shooter, Destiny.
