Blood Bros. is a 1990 arcade game developed and published by TAD Corporation in Japan and Europe, and later published in North America by Fabtek. It is a spiritual sequel to the 1988 game Cabal, with almost identical mechanics. A bootleg of Blood Bros. is known as West Story.
In Blood Bros., two blood brothers, a cowboy and an Indian, team up to hunt down “the most wanted outlaw in Dodge City,” Big Bad John. The gameplay mechanics are extremely similar to TAD Corporation’s earlier game, Cabal, however this game did not seem to have a trackball-controlled variant.
