Challenger — About this game
"Challenger" is an action game consisting of 4 scenes in which archaeologist Challenger chases the villain Don Waldorado and rescues Maria. The perspectives and challenges switch from side-scrolling battles on a train, to a top view of a vast island, to a cave with a fountain, and to a final showdown. On the island, you need to collect keywords and open the way to the cave, and the key to success is to shoot a single knife and judge the enemy's movements.
