While not officially announced in the usual manner, Square Enix seems to be bringing Dragon Quest Heroes: The World Tree’s Woe and the Blight Below to PC through Steam. While the Steam page for the game itself isn’t live yet, the bottom image popped on the Steam client page with the image ad redirecting you back to the main page.
No other information, like release date, has been stated. Dragon Quest Heroes was released on the PlayStation 4 last month in North America and Europe.
