Ep 12. Tunnel Vision

In Transformers: Prime season 2 episode 12, titled "Tunnel Vision," the Autobots must work quickly to prevent the Decepticons from unleashing a powerful weapon. The episode begins with the Autobots discovering that the Decepticons have built a tunnel beneath the city. They quickly realize that the Decepticons are planning to use this tunnel to transport their latest weapon, a powerful energy source known as Dark Energon, to their base.

The Autobots know they must act fast to stop the Decepticons before they can use Dark Energon. They split up into two teams - one to monitor the entrance to the tunnel, and the other to search for a way to stop the energy source from being transported through the tunnel.

Meanwhile, the Decepticons have already begun their plan and have sent a group of Vehicons to escort the energy source through the tunnel. They are being led by Starscream, who has been tasked with overseeing the operation. However, things quickly go awry when the Autobots ambush the Vehicons, forcing them to flee back to their base.

Back at the Autobots' headquarters, Ratchet manages to decode the Decepticons' plan and discovers that they intend to use Dark Energon to power up their latest weapon - a giant cannon. The Autobots know they must destroy the cannon before the Decepticons can use it, but they also know that it won't be an easy task.

The Autobots decide to split up into three teams. One team will keep watch over the tunnel entrance, another will search for the location of the cannon, and the third will destroy the cannon once it's been located.

As the Autobots begin their mission, they encounter a number of obstacles and setbacks. They first come across a group of Decepticons guarding the entrance to the tunnel, and are forced to engage in a heated battle. They manage to defeat the Decepticons and continue on their mission.

The Autobots then split up into their three teams and begin searching for the cannon. One team manages to locate the cannon, but they are quickly discovered by the Decepticons, who begin firing on them.

Despite these setbacks, the Autobots do not give up. They continue to press on and fight to protect the city from the Decepticons. In the end, they manage to destroy the cannon and prevent the Decepticons from using Dark Energon to power their latest weapon.

Overall, "Tunnel Vision" is an action-packed episode filled with intense battles and high-stakes missions. It showcases the bravery and determination of the Autobots as they work to protect the city and stop the Decepticons from wreaking havoc.
