Diablo 3: Reaper of Souls is coming very soon for the PC and Mac, and will shortly follow the closure of the controversial Auction House. The new expansion pack brings a ton of new features including a new Crusader class for players to smite enemies with. Check it out above in the newest trailer.
The Crusader, despite the name, actually specializes in defense and wields large weapons to that effect. He can also use Holy magic because of course he can and take advantage of the new Flail weapons.
Along with the Crusader class, you can look forward to new loot, enemies, a brand new campaign, the Adventure mode and much more. The story continues right off from the end of Diablo 3, with the fifth act taking you to Westmarch and Pandemonium Fortress in order to weed out the bad guys. Reaper of Souls will be out March 25th for PC and Mac, and will release alongside Diablo 3 on PC later.
