---StarCraft II Q&A Batch 31--- Gameplay Blog: This past week while playing a Terran versus Terran mirror game, I discovered a new unit option from the Factory. This new unit is known as the Jackal, which is a fast vehicle like the Vulture, but instead wields a rail gun, which does an area of effect damage in a straight line at ground units. My opponent built the standard Marines & Medics (M&Ms) composition while I bunkered my choke point and teched straight to a Factory with a Reactor add on, which allows me to build two Jackals at one time from a single Factory. --- End of Transmission ---
