Aion OST - Team Crucible Arena 

This is the music that plays in the Team PvP Arenas of 3.5
This consists out of 6 different pieces of music.
These soundtracks are against the regular style of all the Aion music. That's mostly orchestral or instrumental. This is Rock, Metal and some Dubstep
Disclaimer:
I made the screenshot itself from the game.
The music belongs to Aion, NCSoft
