World of Tanks has been a very popular gaming franchise, and publisher Wargaming launched World of Tank Blitz on the Mac through Apple's Mac App Store this week. World of Tanks Blitz allows players to fight each other with tanks modeled on more than "200 legendary armored vehicles." This is a "free-to-play" game, meaning you can download it for free, start it for free, and goose your experience with in-app purchases. The OS X version of the game is cross-platform, meaning you can play with the rest of the World of Tanks universe on iOS, Android, and Windows. It works on Mavericks and up.
