Here's what they have to say for themselves:
DDCE is a beer 'n' pretzels game of areans of death, fast hooves, and deadly weapons. Each player gets a custom hybrid to gallop and slash their way to victory. Make sure you plan ahead, or momentum may get the better of you. Of course, that's better than your opponents getting the better of you.
And why not? It does look like it will be rather fun to play.
