Weapons Concept

Weapons used by the Marines were based on real, fully functional weapons. Brixish armorers used guns they found to be the most reliable when firing blanks and those which looked futuristic. The 'pulse rifles' were created from a Thompson SMG, with an attached forend of a Franchi SPAS-12 shotgun and a Remington 12 Gauge Model 870P receiver with barrel. The 'smart guns' carried by Vasquez and Drake were based on the German MG-42 machine gun and were maneuvered with Steadicam-like harnesses created using old motorcycle parts. The crew found flamethrowers the most difficult weapon to create and use, as they were the heaviest and most dangerous.
