Today at a Gamescom press conference, Blizzard announced the Reaper of Souls expansion pack for Diablo 3. Game Director Josh Mosquiera took the stage to reveal a new class, the Crusader, a burly and heavily armored character. Reaper of Souls will also feature a new act and new endgame options.

Reaper of Souls centers around Malthael, the angel of death, who has seized control of the black soulstone, which houses the soul of Diablo himself. Blizzard promises a "darker" game this time a round, and Malthael is certainly dark, able to siphon souls from the people of Sanctuary, even allowing him to turn citizens into his minions. Of course, Reaper of Souls will include new monsters, including fallen angels.

The expansion takes place in Westmarch, a sprawling city environment. The city has its secrets, including something called Death Orbs, which don't sound very safe at all.

The Crusader class is a holy knight, not unlike Diablo 2's Paladin. They are described as "a war machine made human. The Crusader packs skills like shield bash and a deadly technique called Falling Sword, which basically turns the Crusader into a bolt of lightning crashing down from the heavens.
