The Diablo 3 expansion Reaper of Souls is coming later this month, adding a raised level cap, closing the Auction House, and introducing the already-patched Loot System. It’s even adding a new Act, but lead content designer Kevin Martens says the primary feature is its new Adventure Mode.
"I would call Adventure Mode the primary feature of the expansion," he told PC Gamer. "That said, I think Act V is our best act, so we did take everything we learned there. And you do have to kill Malthael once with one character before Adventure Mode is unlocked. But knowing that you don't have to play story mode over and over again allows people to relax and just enjoy Act V for what it is; and they may or may not come back to it after that, but they don't have to. It doesn't feel as onerous to sit through those things."
He also said that the Adventure Mode has let the team add much-need replayability, which he feels was missing from the main game. "You don't just kill Malthael anymore and the game is done. And I think that was a little too much the case, unfortunately, in Diablo III," Martens said. "That's not the case anymore. When you kill Malthael, now you're finally starting Reaper of Souls. As good as Act V is, once you get into Adventure Mode and you see the promise of everything random that Diablo does; that makes replayability the point of the game. It's not linear anymore so you're experience is different everytime you come in."
