Not enough games to download via Xbox Live Arcade. Here are some more. Atari announced the launch of Centipede and Millipede, two of Atari's best loved arcade classics, available now to be downloaded and played through the Xbox 360's Internet service, Xxox Live Arcade.

"Atari's 'Centipede' and 'Millipede' on Xbox LIVE Arcade are great examples of classic games taken to the next level. The evolved versions of both games provide gamers with the gameplay they know and love, and are now stunningly rendered in high definition graphics," said Chris Early, product unit manager for Microsoft Casual Games. "Now that gamers have direct access to 'Centipede' and 'Millipede' through Xbox LIVE Arcade, it will be easier than ever for fans of all ages to enjoy these classics just like gamers did in neighborhood arcades decades ago."

Centipede challenges gamers to defend their villages against an onslaught of centipedes, spiders, army ants and more. However, XBLA also provides gamers with an evolved version which features pre- rendered, high definition graphics, special effects like motion blur, trails and particle-based explosions.

In the original Millipede, a chain of arthropods that creep down from the top of the screen is the primary challenge, while scattered mushrooms are the gamers' main tool to shoot, destroy and redirect the menacing millipedes. The XBLA version of Millipede has updated graphics. Nothing more, nothing less.
