This sounds rather fantastic and as I hear it I think this would make a great alternative finale song for the last one you face in the tournament while playing the games. Has a hyped up feel to it motivating you to push on and defeat the foe.
The main synth has a bit of a crunchy guitar sound to it with some slight reverb added to it for an atmospheric effect. The drums are simple and work well with the song. Really enjoy the main synth rhythm that most people know and enjoy. The bass is also very relaxing.
Overall, great cover!
