Boneyard: Intro - Call of Duty: Modern Warfare 2 : Hans Zimmer
Even if you're not a Call of Duty fan, this track strikes me as both intense and emotional for a war game. It's used in several places in the game, but for all of them, it fits pretty well and sets the mood for the firefight. I don't play too many Call of Duty games anymore and most of the music seems pretty much the same, but it's the few rare gems that stick out. Gems like this one.

Invasion: Intro - Call of Duty: Modern Warfare 2 : Hans Zimmer
First, watch this mission briefing video. Russia intercepts USA's surveillance systems and unleashes a sneak attack. A northern Virginia suburb suddenly becomes a war zone, and US Army Rangers are deployed to deal with the threat. This track perfectly grabs you by the heart as you become a soldier, seeing what was once a peaceful and normal US suburb suddenly become a battlefield that quickly falls apart around you as the defending US soldiers struggle to fight the opposition. I have played a LOT of first person shooters, but moments like this are rare.

Junk Garage - The World Ends With You : Takeharu Ishimoto
The World Ends With You has a LOT of great soundtracks (some are a bit repetitive, but no biggie). I like this one a lot, which is usually played for the optional boss fights. There's something about the beat, record skips and vocals (not sure what is actually being said besides "baby, baby"), but it definitely gets you pumped and ready to take on just about anything, which is great because some of those boss fights NEED that. I like this track for that.

Extol - Tetrisphere : Neil Voss
Tetrisphere was one of those fun puzzle games and had some good techno-style music tracks, but I LOVE this one and played and replayed it constantly for just about every round. Awesome beat with great energy, I even almost got to use this track for a job presentation video, as my boss really liked it and felt it fit well with the style of the video. However, the big issue was the presentation was much shorter than the song, so we resorted to something else. Still, it's a great track!

In The Zone - Extreme Road Trip 2 : Big Giant Circles
A great techno-style soundtrack from a smartphone game? Why not? This is a great example of how much difference a great music track can make, as the game is relatively simple, but the music gets you PUMPED and very energetic.

Goteki TS Remix - TimeSplitters 2 : Graeme Norgate
It starts off a little quite and loopy, but wait for it... wait for it... and then you get energized by the beat and the "no clue what they're saying but it sounds cool" vocals. TimeSplitters 2 is a gold mine of great tracks, but this is definitely one of the best ones.

Super Power Theme - Advance Wars Dual Strike - Yoshito Hirano
This theme doesn't mess around. It starts loud and stays loud, and it's oh so much fun to listen to as you make mincemeat out of your enemy's armies. The big drawback was that it only played during the use of Super Power, which was rarely used when you could just build up more toward the Tag Power, which was much, much stronger. Still, I like this theme anyway.

Max Kill - Max Payne 3 - Health
This awesome track is used for a action-packed boat level in Max Payne 3, and it works great by setting the dark and gritty mood while still upbeat for fast and ferocious action. I've beaten Max Payne 3 several times now, but I use this track for my Battlefield 4 playlist (Battlefield 4 has no multiplayer music). It works really well there too!

Tears (Game Version) - Max Payne 3 - Health (Alternate Soundtrack Version)
"Tears" was nominated as Best Song in a Game at the 2012 Spike Video Game Awards. It's not hard to see why. Suddenly, a whole corrupt police force has you pinned down in an airport and you're out for revenge and to take down a morally corrupt politician (avoiding spoilers). Only your wits, grit, determination, and the guns in your hands will get you there. This track with its pump-it-up beat and great lyrics does an AWESOME job of capturing that intensity and mood. It's a shame it only plays for a short while, but still, it's one of the best tracks in the game.

Drop Dead - Twisted Metal - Chuck E. Meyers
This is a FANTASTIC and INTENSE theme, especially considering you fight the final boss (a massive tank called Minion that is slathered with weaponry) to this on city rooftop, where it's easy to fall off and plunge to your death. Definitely one of the best last boss themes I've heard and doesn't hold back when giving you an intense and pounding track to fight hard with.

New York (The Big Leap) - Twisted Metal 2 - Chuck E. Meyers
Fancy some intense and insane rooftop vehicular combat above New York? This has you covered and the soundtrack is intense and fits the game and the map perfectly. If fast and ferocious combat is your thing and puts you in your happy place, this is another great one to add to your playlist. Play it loud!
