Bob is a turret from Aperture Science.
He's slow and he has a bad aim.
One day GLaDOS told him to kill some random b17ch called Chell.
He stayed in chamber 16 waiting for Chell, and when he saw her, he shot her, but as I said before, he was slow and had a bad aim (ie, he was a l00ser) and she scaped.
What a fag.
Now the important part:
Chiptune related instrumentation:
-Square Wave 50%
-SID Lead
-White Noise
-Square Wave 25%
-Sawtooth and Square Waves for the wobble bass
-Sinewave Bass
I used samples from the Turrets from Portal too.
