Capcom has announced the impending arrival of another World Warrior to the iPhone's Street Fighter IV: the almost formally dressed spy, Crimson Viper. She'll be added to the fighting game through a free update, in the same manner as previous additions Cammy and Zangief. You can see a clip of Viper in action after the break, courtesy of IGN.

Capcom has yet to date this DLC, so you'll have to play Viper-free for now. In addition, Capcom hasn't made any announcement about a downloadable arcade stick for the iPhone, probably because that technology doesn't actually exist.
