Tracer Fire

The Tracer Fire torso are produced by Neuropa. This torso have two little guns attached on its back, which can shot two short laser beams at surface enemies as well as the enemies on sky. It's a good long-attack torso for use since it can attack at Jets , Bomber, or Jet-Packed Combots (with a Jet Pack or Jet Boots).

The Tracer Fire Torso deal high energetic damage, and have a minor effective kinetic damage. They are somewhat comparable to the Flak from Mil-Agro and Drunk Missiles  from Rimtech.

Official Description
"The Tracer Fire Torso contains two medium-sized cannons that fire super sonic titanium bolts. The addition of a liquid coolant system prevents the guns from overheating, which, in tum, gives the shots a "tracer"-like look when fired."
