Activision's famed Call of Duty series has relatively few mobile entries, but it seems that Tencent is working directly with Activision to develop a new mobile game for the franchise. The game will be a first person shooter that brings together a number of the series' most celebrated maps, characters, weapons and modes, according to Tencent. It will also be free to play, and will be a full-featured first person shooter in the usual style of the franchise.
