There's two types of the square ones, you see? There's the weak ones, they split along the middle making two thin boxes. Then there's the strong ones. Their boxes don't split, just have one big flat face on one...uh...face. "Quad-drones" or somethin.' Don't mess with them. The weak ones are barely aware, you can probably just walk right past 'em as long as you look like you're s'posed t'be there. Quads...they know you ain't s'posed to be there. And they don't like nothin' that ain't s'posed to be there. Had a friend ripped to shreds by their damn buzzsaw arms...and the weird thing was, it was like they always knew where he was goin' before he even wanted t'go. Jus'...stay away from them quads. You'll live longer. Instinct: Obey its orders exactly
