Superb sound and visuals grace SPACE INVADERS EXTREME, a high-definition experience that stays true to the Space Invaders aesthetic. The XBLA version comes with an added bonus: the Visualizer System, where the music subtly changes as the background movie changes. You'll also be able to challenge other players over Xbox LIVE, including in Score Attack mode, as well as play cooperatively to take on the invaders as a team! There are no refunds for this item.
