Any advantage to buying the Styx Bundle?

I got Master's Of Shadow when it was a free game. Haven't played it yet, but I will soon as I've heard it was fun. Because of the current sale, the new Game Shards Of Darkness is $29.99. The Bundle with both games is only $2.40 more. Is there ANY reason to buy the bundle if I already have the 1st game? Does it come with any DLC? Thanks!
