Those invaders from space, they landed. Turns out that Earth is a pretty cozy place, but you have a housewarming gift they're not going to like. Hop in your Solvalou and take back Earth in Xevious, part of the NES Classics Series.One of the first vertical-scrolling games, Xevious calls for you to man your aircraft, the Solvalou, shoot air targets and bomb ground forces. You'll need to blast the motherships in order to send the aliens packing. No need to worry about trigger-finger fatigue. Just hold down the buttons for repeat weapons fire.Find the hidden Sol Citadels, silo-like structures, to score big points. Special flags are also hidden in the game to give you an extra life. If you progress through at least 70% of a given area and lose your ship, you'll start at the beginning of the next area. If you don't make it far enough, you'll have to start over at the beginning of the area.
