There are lots of Diablo-looking action RPGs in the world today, so how do you make your new game stand out? Local co-op is a good step, but co-op's no rarity either. What if the players could turn from guys into animals and ride each other around, though? Now we're talking! That's Coridden, an upcoming Steam game from Aftnareld, which is totally the name of a company, so don't even ask. The game won't be out until next year, but you can try the demo right now.
