Dillon's Dead-Heat Breakers is a video game developed by Vanpool and published by Nintendo for the Nintendo 3DS. It was released in Japan in April 2018, with English releases in North America, Europe, and Australia the following month, with the North American version being limited as digital-only. A sequel to Dillon's Rolling Western, it takes place in a post-apocalyptic world and features Dillon, an anthropomorphic armadillo who must defend frontier villages from walking rock-like monsters. The player is included in the game's cast as their Mii avatar in the form of an "Amiimal" with added animal features from various species. It received mixed reviews from critics, who most greatly criticized its repetitiveness.
