New Structure — Nuclear Silo
Nuclear Silo produces advanced MK2 Nukes and requires war-factory components to stay operational. The structure uses 2 timers:

1. Silo Operational timer - defines for how long the building is active and producing MK2 Nukes) and
2. MK2 Nuke production timer - required time to produce 1 MK2 Nuke).

Once produced, MK2 Nukes are available directly in any battle-mode. Only one MK2 Nuke can be stored in Nuclear Silo at a time. Hence, you should quickly deploy your MK2 nuke so that the production of the next MK2 nuke can start.

New War Factory Power-UP -Iron Dome
Iron Dome can be crafted in War Factory using components and applied to any 1 Patriot on the base. Once the boost is applied, it will surround nearby structures with a field that mitigates damage dealt by any enemy's Nuke. Iron Dome is invisible for the enemy until it is damaged by a Nuke.
