· The hidden Sol Citadels are not in the same locations as they are in Xevious but they can usually be found along the same horizontal line as the original.
· There are also four special flags hidden at certain points in the game. Uncovering and flying over a special flag will award an extra life. The targeting sight will not flash when it is over a hidden flag.
· BUG: Three of the new enemies - a dark yellow tank, a helicopter on the ground, and a small jet taking off from a runway - should not be destroyed. Destroying any of these enemies resets the score to zero but flying over the tank or helicopter awards a 10,000 point bonus.
