Activity Features Three Kinds Throwback
The activity features three kinds of throwback dungeons, but the type I'm most interested in are the Prime Evil Waking Nightmares, which recreate "the most iconic moments, the moments that lead up to you killing Baal, Mephisto, Diablo."
"The last one, and the one I'm probably the most excited about, is actually a recreation of almost all of Diablo 1, so you start in Tristram Cathedral, fight your way to the Catacombs, down to the caves, and then of course into Hell itself to take down Big Red, the Dark Lord, Lord of Terror, Diablo."
