Digimon Heroes! (デジモンクルセイダー,Dejimon Kuruseidā?, lit. "Digimon Crusader") is a Digimon video game for the smartphone, which serves as a sequel-of-sorts to the Digimon Jintrix digital card game. It is part of the franchise's fifteenth anniversary. Service for the Japanese version of the game ceased on November 26, 2014. It was translated for English release in 2016, but retained the original Japanese terms for characters and concepts rather than their localized alternatives.
Digimon armies from all corners of File Island have been in a perpetual struggle leaving the island in ruins. Unhappy with the state of the world, Ophanimon summons you – a crusader – to the Digital World. You get a pack of energy cards and are given the task of uniting the island.
