"Astro Wars was a simply brilliant variant on Galaxians produced by Grandstand and released in 1981. At the time Grandstand were the dominant force in hand-held games although this lead would soon be ceded as the game/watch hardware from companies like Nintendo became more prolific. Ultimately people turned to the cheaper, varied and generally better computer/console games. Still, this is a beautiful little unit which kept me occupied for many hours.
