Sky Odyssey — the player is given control of 10 different aircraft, 7 of which must be unlocked. They range from real aircraft, to prototypes that have never flown in reality, to completely fictitious ones. Although some of them are military aircraft, there is no actual combat taking place in the game. Instead, players are tasked with completing challenging missions to find map fragments needed to find the Tower of Maximus. Most missions involve moving from one point on the game map to another, but rarely does this happen in a straight line. Missions often follow a path that requires flying through extreme terrain such as canyons, caves, and mountain peaks.
