The majority of tracks are videogame music covers but there's also a couple of non-videogame covers and an original composition.

In terms of style or genre it's all mostly metal but you can expect a bunch of varied elements from other things ranging from folk and orchestral to electronic and industrial. Some tunes might be too smooth and cheesy, some might be too brutal and agressive.
