Not bad, although it could be a bit more creative and it sounds like the voice is just pasted on top of the music. The beginning of "Defcon 5" sounds horribly similar to "Unparralelled" (plus you got it wrong, it should be spelled "Unparalleled"); again, could use more creativity. Didn't pay much attention to the lyrics, so those are getting reviewed separately sometime later.
The best song (imo) is "Why" (i'm not counting the samples koz i don't like to download incomplete songs, so i'm comparing the three full songs i was able to download).
Overall, i think it has potential to evolve into some kind of Killswitch-Engage-style guitar+screaming with power metal bridges (not solos, since there's drums and bass on the background; i don't know why people keep calling them "solos"). Maybe work a bit more on the creativity and on melding the voice and the music a bit better. Keep it up, and keep us fans informed.
