Did you know that today is Ninja Day? No joke. So what better time for Electronic Arts to official announce Ninja Reflex, a "party game" coming to the Wii and Nintendo DS in Marcy 2008.

Developed by Sanzaru Games and co-published by EA Partners and Nunchuck Games, Ninja Reflex is a martial arts-themed collection of mini-games that challenges gamers' reflexes and measures reaction times. The game also features multiplayer modes, where players can battle with up to four players for "ninja supremacy."

"Ninja Reflex channels the accessible multiplayer fun of Wii Sports, and the self-improvement aspects of Brain Age into a martial arts universe that is ideally suited for the Wii and Nintendo DS," said David Luntz, President and CEO of Nunchuck Games.

Destructoid's Tiff Chow infiltrated the ninja camp to sneak some time with Ninja Reflex, so keep your eyes peeled for more information later today.
