Cobalt Bomb

"DESIGNED FOR MAXIMAL FALLOUT. THE INSIDIOUS COBALT BOMB."

The Cobalt Bomb is a Superweapon inspired by a hypothetical bomb of the same name.

This missile deals no damage, but instead its fallout causes a nuclear winter, forcing nations within its radius into cooldown for 60 seconds.

Strengths

 * Very fast build time.
 * Can be used as support (preparation for own First Strike) or defense (delaying an enemy First Strike).

Weaknesses

 * Only usable as support.
 * No indication of whether affected nations are owned by a Superpower without Tactical Highlighting.
 * Affected capitals can still deploy superweapons (this may be a bug).
