hmm...
im a serrious gamer and if this were to be remixed you could take out the techno, its not needed, The guitar needs to be higher, the body needs to be a little more in the lines of the actuality that makes it halo, this actually reminds me more of Contra not Halo,
but hey you worked hard on it i presume and therefor i give you a ten on effort on trying to bend the gravity of Halo itself. This peice however deserves to be deemed as fantastic.
sorry to be a bit rash in the first paragraph. thanks for reading.
