This week on Xbox Live Arcade  you can get hold of Asteroids and Asteroids Deluxe by Atari.

Anyone who has played the originals will know all about these games. The objective of Asteroids is to score as many points as possible by destroying flying saucers and space asteroids. The player takes controls of his ship which can rotate left and right, fire shots straight forward and also thrusts forward. Simple addictive retro fun, if you like that sort of thing.
