Tank! Tank! Tank! free-to-play in Japan

Tank! Tank! Tank! has not been performing well with sales and as a result from that it has gone free-to-play on the Wii U eShop. The free version does not contain all of the maps or a campaign mode. However, this extra content can be purchased and added to the free version.

Hopefully, this goes outside of Japan and encourages the developers to make more content for the game.
