In Beyond Divinity, the arch demon Samuel has bound your soul to that of a Death Knight. While opposites in terms of alignment and personality, the two of you agree to work together to escape the curse.
You choose one of three classes (though you can customize and mix them through your choices): Warrior, Wizard and Survivor (Rogue). As mentioned above, you also get the Death Knight as a henchman, and can use summoning dolls to get temporary party members. You can customize the skills of all of them.
The game offers addictive action You can control either one of the characters, or both. The other character will auto-attack. I picked a Wizard for the main character and actively controlled the Death Knight. While the Death Knight ran around the enemies, my Wizard hit them with spells. While the action was a lot of fun, the game is more than just hack-and-slash. There are meaningful dialogue choices, puzzles to solve, etc.
The graphics are quite good (check out the screenshots), though I would have preferred some more variation in the backgrounds.
The music was nice and added to the immersion in the game. The voice-acting was also generally good, with some exceptions.
Overall, this game should offer hours of fun to anyone looking for a good hack-and-slash with considerable depth.
