Six Atari titles have been announced for the downloadable games service, and each will come with classic and "evolved" versions, in addition to standard features like leaderboards and achievements. The half-dozen games set to release include Centipede/Millipede, Battlezone (with new multiplayer modes and Xbox Vision camera support), Asteroids/Asteroids Deluxe, Missile Command, Tempest, and Warlords (which lets gamers import pictures for their castles). No prices were announced for the games, although older arcade games on the Marketplace have generally been priced at 400 Microsoft Points ($5).
