Project X Zone has been described as a game that one should simply play in order to understand. Fortunately, gamers in both North America and Europe will have the opportunity to sample this Capcom, Namco Bandai, and Sega crossover title before it launches.
The so-called Project X Zone: Imperial Demo (called A Lethal Surprise in Europe) is currently available on the European 3DS eShop, and will arrive in the North American eShop on June 4.
