The latest additions to Xbox Live Arcade have been announced. Konami's Contra launches this Wednesday while troubled Atari rummage through their back catalogue once more for January launches of Centipede/Millipede, Battlezone, Asteroids/Asteroids Deluxe, Missile Command, Tempest, and more interestingly, Warlords. So, fairly dull unless you fancy the five minutes of nostalgia that these retro games normally offer. No, the real excitement on Live will be Sensible World of Soccer - my tip for a potential game of 2007, assuming developers Codemasters don't tinker with it too much.
