Darksiders II will be out next Tuesday, so we see the last "gameplay" trailer today. Not actual raw gameplay (hence the quotations), but some gameplay footage featuring the one and only Death.
Despite the whole "gameplay" bit, we do actually get insight into the story. If you hadn't already heard, Death is on a mission to vindicate his brother, War, who is currently imprisoned for crimes he didn't commit. This sends him on quite an adventure and pits him against creatures of mammoth proportions. Death loves his brother that much.
In the trailer, we do see the Guardian, made famous by this CG trailer released a while back. So yes, he will be showing up in the game.
You'll be able to face him yourself come August 14. Well, maybe. It's a big world Death finds himself in.
