Excerpt: Tower Defense games have become all the rage in recent years. The concept is pretty simple. Bad guys go walking along a path, and the player must put things along the side of the path that will stop them. In terms of this Wii game from Crave Entertainment the tundra up north is the location. Penguins have fish in their villages, and the bad animals are walking through stealing them. So put up snowball throwers, snowman launchers, icicle shooters, and more to stop them.
