Challenger (チャレンジャー, Charenjā?) is a video game developed and published by Hudson Soft in 1985 for the Nintendo Famicom. The title character, Challenger, is an archaeologist who seeks to rescue the princess, Maria, from the hands of the evil boss, Don Waldorado, in the land called Pleasio Land. The setting of the character as an archaeologist is an homage to the Indiana Jones franchise. The scene in the first level where the princess is taken away by the villain is programmed as part of the level, and it is impossible to catch up to the princess no matter how quickly the player progresses. The background music for this level is an arranged version of the well-known military march by Franz Schubert. Source: Wikipedia, "Challenger (video game)", available under the CC-BY-SA License.
