Minigun

The Minigun was an extremely powerful rapid-fire chaingun capable of decimating any weaker zombies very quickly. This weapon was not cheap at $2,500, but it's zombie-mulching effectiveness was increased further by upgrading a Minigun with steady aim and ammo belt upgrades. It used 150 rounds at first, but after obtaining the "Quarterback" skill, it got 10% more ammo, then 20%, 30% and so on. this gun was effective when used in conjunction with a Flamethrower for additional crowd control purposes.
