Kamchatka Peninsula

The  Kamchatka Peninsula  is a region in east Russia, known for its volcanic activity.

"Operation: Breakdown"
MECH used an energon signal to lure Bulkhead  and Breakdown  to the deserted Kamchatka Peninsula, long since abandoned by humans following a volcanic eruption there twenty years prior. The two enemies fought in a ghost town until Breakdown prevailed and was set upon by Silas' s men. They took him to a nearby abandoned rail tunnel where they had set up a makeshift base and set about dismantling him. The Autobots turned up and began searching the town. In the courtyard of a large building, they found Breakdown's right eye, which turned out to be the lure for a MECH bomb. Bulkhead, meanwhile, located the MECH base in the tunnel and busted Breakdown out. A battle ensued between MECH and the two Transformers, which ended when Starscream  arrived to chase the humans  off, and then Prime's team arrived to do the same to the Decepticons.
