Fury of the Empire

Fury of the Empire is the thirteenth and final main challenge in Commander's Challenge. Completing this mission finishes the Commander's Challenge storyline and unlocks the ending video.
==Briefing==
The Empire of the Rising Sun's Giga Fortress may be the most advanced weapon ever developed, so we would very much like to have a look at it. And we know that you of all people must have what it takes to crack a couple of them open. Commander Takara will be waiting--she knows what we're after. You've already brought us so far. But if you can do this, our R&D will catapult a century ahead. In which case, we'll have something special for you. Come back soon. 
==Overview==
* Although the fog of war is active, the player will still have several small areas of vision around specific parts of the map: the center, the Airports, the top-left corner and the bottom-right corner of the map. These areas have a Giga Fortress present (and in the corners of the map, they are each accompanied with two Naginata cruisers) which will attack the player's units if they are nearby but will not pursue them. 
* During intervals, a Giga Fortress along with other accompanying Imperial naval units travel along the opponent's base island. They move in a fixed path and will attack the player's units if they're nearby but not pursue them.
* If using Allies, use Spies to bribe the Giga-Fortress and a Naginata Cruiser in the corners of the map. To gain vision of enemy infantry units for the Spies to disguise as, use Surveillance sweep.
