Transformers: Fall of Cybertron
300px-Guardian attack mode foc

The Guardians patrolled the Decepticon-controlled ruins in the Sea of Rust under the orders of Shockwave in anticipation of Autobot snoopers. Autobot snoopers did arrive in the form of Cliffjumper and Jazz. While the Guardians' sensors (known as Stealth Crackers) proved capable to see through Cliffjumper's cloaking ability, the Autobot's skill allowed him to sneak up and defeat the Guardians with ease.
