A weapon more sinister than the flamethrower. The G21 HPW (short for Heavy Bio Weapon) is a weapon that's as effective as it is disturbing. What it sprays is a heavy stream of hydrofluoric acid at an effective range of 35 feet and is able to burn through almost any surface. The ammunition source comes from a canister on the under belly of the weapon, but can be hooked up to a massive backpack for extra fuel. Two major draw backs of this weapon is that it is obviously heavy and if it's containers break....... well, take a wild guess.
