Activision is switching things up for its cash cow franchise, taking it from Steam, PC gaming’s biggest digital distribution platform, to Battle.net.

The platform switch was revealed during the game’s debut event earlier this week. According to Activision, the game will be “fully integrated” with Battle.net’s social features (which, you know — I’d certainly hope so).
