Blizzard released 10 new Diablo III screenshots featuring the Barbarian, the Witch Doctor and the Monk traveling through the desert and some desert dungeons. We can see a few new mobs. One resembles the naga, and the other ones look like spider-like humanoids.
Some fans will have different opinions, but I gotta say I hope this blood is a placeholder. In screenshots it doesn't look good. Regardless, it is clear that Diablo III will be a game of complete carnage soaked in blood.
