Classic NES Series: Xevious Cheats

Shortly after you reach the first set of spinning walls, you'll reach a lake. If you dump bombs into the lake, a flag with an ''S'' on it will appear. Flying over the flag will give you a free ship.

Just before you get to the Fortress pause the game. Unpause the game, but instead of sticking around to fight the Fortress, you'll be able to just move right past it!
