The fierce firepower made Laura Croft gasp in amazement. The automatic feeding system continuously fed ammunition belts into the Heavy Explosive Rounds, which then spewed them out at speeds too fast for ordinary eyes to follow. Massive shell casings rained onto the roof and roadside as the Armored Personnel Carrier jolted along. "It's a machine gun!"
