The de-rigueur gangsters' sidekick, the Tommy Gun spits plenty of lead from its sizeable drum magazine, putting a lot of metal in the air, eliminating large groups of enemies with ease and causing much general carnage. While not boasting the fastest rate of fire out there, it makes up for it with good stopping power. Wielding two Tommy Guns akimbo also more than makes up for whatever the weapon may be lacking when used on its own. The Tommy Gun has appeared in TS and TS2. In TS2 story mode, it is in the level Chicago.
