Goliaths offline. The Dominion recognised a critical weakness in terran anti-air defence during the long brood wars. The viking was set into fast-track design to plug this hole. Based on the transformation design of the Arclite and Crucio siege tanks, the viking has been conceived as the ultimate anti-air and ground assault-support weapons system. The viking has the ability to transform from an assault walker to an air-superiority fighter, and with it the ability to change the tide of the battlefield in favour of the Dominion.
