The Autobots have secured the surface of the Fortress and are now striking for the center, while the Decepticons are making their own significant progress through the ice to reach the middle of the frozen fort before their enemies.
Fight your way into the heart of the Fortress for Alloy, Spark, 3-Star Shards, Nano-frost Battle Boosts and Nano-frost Crystals!
