It’s both. For PvE we add a full story arc told through story missions (even though it’s a linear story I am reluctant to all it a campaign because it’s co-op, not single player). We’ll also have Hero Missions (which are highly replayable PvE backed by a progression system). The closest analogy (although neither is quite accurate) is Adventure mode in Diablo III or World Quests in WoW (again, not a great analogy but indicative of the level of replay we’re hoping for).

For PvP we’re adding a completely new pool of PvP maps including a new game mode called Push.

For both modes, new heroes will be added.
