Nidhogg mobile artillery

Nidhogg - is the heavy artillery system of the Asgard in Red Alert 3: Entropy

Background
Nidhogg is the embodiment of firepower in metal. In a mobile state, this artillery system is not capable of attacking. Being stationary, Nidhogg deploys three ranged weapons that fire plasmoid balls, dealing chain damage on hit.

No tank capable of efficiently withstanding the damage of Nidhogg projectiles. As if this were not enough, the plasmoid hit is spread to all nearby targets, in turn transmitting damage to other targets. Due to the domino effect, it is possible to destroy entire armies if they are in close formation. However, the hit damage gradually decreases.
