Katarina and I finally got through the story. 12 chapters in all which is just huge considering Diablo 3 has 5 Acts which each Act equals about as much content as 1 VH Chapter. The final boss was epic to be expected. The only difference between the two games is that in Diablo, they expect you to survive the fight to defeat the bosses. In VH, they expect you to die…… A LOT! It usually takes about 10-15 deaths to defeat a significant boss. You have the option to pay gold to rez and continue the fight where you left off. This is the only way as it is impossible to defeat a boss without dying in this game.
Ive started doing VHs equivalent to Adventure mode now and it seems pretty cool. Its similar to D3 as far as new maps and challenges.
More on this later as I investigate.
