Burrower

 is a vehicle of the SUN.

Background
It costs 3000 Resources and five Butanium to build this underground transport. Any unit with a Construction skill level of two and a Building skill level of two can make a Burrower. This ingenious vehicle can move slowly over the surface of Yavaun, but they serve best as a means to tunnel beneath impassable terrain or enemy forces and surface at any designated spot. By left-clicking on the Burrowing icon, then a destination square, a Burrower digs underneath all obstacles to that location. The Burrower's ability to move undetected has proven useful in executing small covert missions, hitting the enemy where it is least expected. Burrowers can carry up to two Units.
