This is not heavy metal.
In fact, it's the following things:
A simple drum beat
A one-measure, five note bass riff
A gun firing and cocking
A guy screaming sporadically
Where is the heavy metal? The drum was definitely electronic, and having been a heavy metal bassist I can assure you that riff is NOT metallic. Not to mention it's extremely repetitive.
It, uh, wasn't bad if repetition is your thing. The sound clarity was rather good, and your synthesiser is rather keen, but it was 2:31 of a gun cocking and shooting, cocking and shooting. Where's the metal? That's all I ask.
