Black/Matrix (ブラックマトリクス) is a series of tactical role-playing games developed by Flight Plan and published by Interchannel. All titles in the series are Japan-exclusive. Each installment in the series combines standard tactical RPG gameplay with a pastiche of Judeo-Christian religious themes, particularly concerning the nature of good and evil and the interplay between Heaven, Hell, and Earth and the denizens thereof. One title was considered for North American release in 1999, and it is believed that it was eventually passed over due to its religion-derived themes.
