At the same time, Starscream is sent to Nepal to find and destroy the remaining MechTech that is about to be airlifted by the massive Aerialbot Stratosphere from a NEST facility somewhere in the snowy mountain range. Upon killing the other Aerialbots - Air Raid, Breakaway and Silverbolt - he destroys Stratosphere mid-air, along with all the technology he is carrying, though he manages to retrieve a weapon and returns with it to the Decepticon base in Siberia, unaware that it had a tracker on it. The Autobots subsequently invade the base, but Megatron fights them off, killing Warpath in the process. He then finds a cryotube holding a frozen Shockwave, the infamous Decepticon scientist and assassin, whom he frees from his imprisonment, before facing Optimus Prime.

As Optimus is fighting waves of incoming Decepticons, Bumblebee escapes, and the pair then flee from the base. Upon being picked up by Stratosphere, the Autobots analyze the information they retrieved from the base, and learn that the
