The Nomad has been revealed at the official Starcraft 2 site. Check out the animations, gameplay video clip and sounds here:
The TF-620 nomad is an all-around workhorse that combines the functions of light manufacturing center and observation post rolled into one. A common sight among the fringe-world colonies, the nomad is a robust, air-mobile vehicle built to operate independently in all but the harshest climates. Although the nomad shares a number of common traits with its smaller cousin, the SCV, the nomad is a far more specialized and advanced engineering craft.
Nomads are normally employed for first-line colony surveillance and protection duties against dangerous local life forms or climate events. These vehicles boast an impressive array of sensors delicate enough to detect even cloaked or burrowed enemies. By deploying its two aft-mounted nano-welders, the nomad can construct a variety of small, semi-permanent defensive structures to meet various threats in a matter of moments.
Several standard template constructions are available to the nomad, a popular example being the auto turret. This simple robot gun emplacement is suitable for driving off smaller hostile life forms for an extended period of time.
The Terran Dominion initially provided nomads to give low-level protection to its most isolated outposts, typically manning them with local civilians as something akin to a volunteer fire truck or ambulance service. Over time the military support applications of the nomad have seen it deployed in escalating levels of conflict, gradually replacing the older and vastly costlier science vessel.
