FanstravaganzaProject X Zone already has an "Imperial" demo available for download on the 3DS eShop, but the game's official Nintendo page says there's another demo coming on July 2. The second demo is called "Ghost" and will give players a look at a completely different segment of the game.
Project X Zone (pronounced "Project Cross Zone," because Japan) is a turn-based strategy RPG that mashes up characters from Namco Bandai, Capcom, and Sega franchises. The game came out in Japan last year, and just recently arrived here in North America.
