Welcome aboard:

"Incendium" mini-cannon

This beauty is about the size of a minigun(or whatever heavy weapons the terrans use that are bigger than their gauss rifles) and fires devestating bio-incendiary rounds. Any biological target hit by one of these rounds(which look more like bullet-shaped fireballs once you pull the trigger) will instantly catch on fire and be consumed by the flames. Smaller targets - like zerglings - will die from one shot while larger targets - like ultralisks - take heavy damage and then perish over time as the flames spread.
Powerful as it is against biological targets it sucks terribly versus mechanical units. The rounds are designed to feed on organic mass and incinerate flesh, so anyone safely tucked away in a Thor, ST, Banshee, jackal, or just about any vehicle(firing at an SCV's propulsion system will blow them up though) is out of harms way, and the same goes for protoss shields.

WHY??!?!?? OH WHY?????? =(

Poor SCVs always get the short end of the stick

sounds good btw

Just wanted to add that I want tac-nukes.

That is all.
