The sequel to Raiden I and Raiden II, RaidenX is a 2D vertical-shooter Flash game. There are 8 levels and this new version allows you to save your game after each level (yay!). On the main menu of the game, go to SETTING then choose DIFFICULTY. There are three levels to choose from - EASY, NORMAL and HARD. Normal should be okay for most players, but choose Easy if you suck; Hard if you rock.
