Energetic in a way that stays consistent but not so apparent or obvious to the listener to where it becomes overly repetitive--there's a fun value to the additional arpeggios or lead instrumentals that overlay the main beat because they contain strong high values in their chords. There's that constant chord progression but there's also a combative consistency to everything else going on that brings a treat to the essence of whatever fighter, brawler, or beat-em-up game that this kind of thematic tie-in is perfect for.
tl;dr "Come on !!!"
The vocals were such a nice added touch that really supplied additional value later on when they became a focal point in the instrumental. NOICE
