SouthPeak has made a demo of its DS game Ninjatown available for download via the Wii's Nintendo Channel.
The demo includes the first six maps from the tower-defence-type game - exactly one-sixth of the final count - and a smattering of the units and abilities you'll eventually have at your disposal.
You can get it by opting in on your Wii to send data to Nintendo, then selecting the demo from the Ninjatown info page. Set your DS to "download play" and off you go.
We recently reviewed Ninjatown and thought it was "very silly" and "deceptively complex". See if you agree.
