New Elite Viking Unit. Inspired by Nova Co-op leader and from her units. Her units are all uses the latest tech, but I didn't see a Viking. I like Vikings because of the game Lost Viking and that they are the only hybrid unit to switch from air to ground.

Attack Ground: 18

Has a +160% HP increase and a +50% ATK increase of a standard Viking made from a Starport. The cost of minerals increased by +150% and gas increased by +153.33%.
If Nova had a Viking in her army then I guess its stats would be what I put. A max squad of 3 Vikings should be good since Mercs comes in 3 as well.
