Dillon's Rolling Western

Dillon's Rolling Western, known in Japan as The Rolling Western (ザ・ローリング・ウエスタン), is a downloadable game developed by Vanpool and published by Nintendo for the 3DS. Released exclusively through the system's Nintendo eShop online storefront, the game features Dillon, an anthropomorphic armadillo who must defend frontier villages from walking rock-like enemies. Dillon's Rolling Western combines elements of 3D exploration, action sequences and tower defense and was first unveiled at E3 2011 as The Rolling Western.

Dillon, an armadillo, is a ranger charged with protecting villages from nightly invasions of walking rock monsters called Grocks. The Grocks attack the villages to feed on Scrogs, the residents' livestock. While Dillon is able to attack Grocks by rolling into them, the Grocks can sometimes outnumber Dillon. Thus, the villages have established defense towers that can be outfitted with weapons that will attack Grocks whenever they are in range. To get guns, you must buy them, and sometimes you may have to build the gun tower first. In order to improve the villages' defenses, Dillon must collect materials by exploring mines and defeating Grocks; the materials can then be used to build stronger doors for the village. The stronger a door is, the harder it is for a Grock to get in.
