Larian's crowdfunded Divinity: Original Sin is available on Steam now for $39.99.
The game features isometric, party-based combat and gameplay which is set in a "reactive, living, and open world" which is said to be home to a diverse range of creatures and many interesting treasures for players to uncover.
Turn based combat allows you to mix up spell and skill combinations to affect the environment and a classless system which enables you to mold your character however you want.
There's co-op multiplayer and co-op dialogue which let you hape your relationship with your partner and will influence the game. Beyond that, there's also a level creator, the same one used by the game designers, that lets you create and share your own adventures.
You can check out the features trailer below though clearly the main reason to buy the game is the Cow Simulator 2014 mod which is included. Divinity: Original Sin has been in Steam Early Access testing since January and entered beta phase in April.
