Me and John Mirra worked on creating this song, as a tribute of sorts for Firearms. You can check it out here:

It took about an hour of work, pizza, and caffiene... aka, it was pretty rushed, considering I spend two to three hours on my own songs. However, if it's well received by the community, we're more than willing to work on a bigger and better version.
Long live FA!
Oh, and PS: Someone already mentioned that it lacks the battlecry sound. This is because I don't have the original -- I replaced mine with "CRRRAAAAAAAB BAAAAAATTTTTTLLLE!"
