From Press Release:
The seasonal update also brings the Contract System and its special challenges. Contracts are specific tasks that are rewarded for completing in both PvP and PvE matches. Players can receive more valuable rewards after completing a series of tasks.
Along with the update were introduced special agents for every class. These are comprehensive themed packages to give your character a wholly new sense of style. Each of the special agents has its own story, themed appearance, and a special set of items, including a series of weapons, armors, trinkets, and achievements. They are specifically made to complement a class and each class will receive a special agent package.
Among new features, Hidden War is about to bring technical adjustments over the course of the season. In addition, the European and North American servers have been merged, so players can access all regional servers. Now developers are getting closer to the merger with Warface CIS and creating one global Warface PC community.
