Way back in 2007, Nintendo released a Flash game called Chick Chick Boom, playable in the Wii browser. Three years later, developer Tons of Bits has completed a WiiWare version of the chick-vs-chick action strategy game, informing it's been submitted to Nintendo for approval.

Chick Chick Boom involves drawing the outlines of weapons to fling them into the opposing team's area. Though the Flash game doesn't appear to be online anymore, you can get a better idea of how it works by checking out the video after the break.
