Activision has released Call of Duty for the iPhone... but don't get too excited, it's not exactly what you think. The first-person shooter hasn't quite been ported yet. Instead, they've released a "Call of Duty: World at War companion," which instead lets you track the activity on the popular World War II shooter game. You can track all of your ingame stats, and even follow your friends in the game and what they've done with their characters as well. And the app also comes with a news browser, to keep you up to date on the latest map releases and updates with the game. It's completely free, though you of course need a Call of Duty: World of War game for Xbox 360 or Playstation to actually get anything out of it.
In that sense, this app isn't quite so notable for what it is (World at War wasn't nearly as popular as Call of Duty 4, and this app is specifically about Treyarch's game), as what it portends: with Blizzard releasing their Armory app and a few other game companies releasing "companion" apps like this, we could be in for a very interesting holiday videogame season this year. Ports or translations of games don't do much to sell copies of the real games (as they tend to be either too similar or too different to the parent games), but "companions" like this can represent added functionality, and thus can do a lot to help and promote games on other platforms (imagine a Halo ODST app that sent you a push notification when your friend was playing or got a higher XP score than you did). This is far from the last we'll see of "companion" apps like this.
