This is not war, it's extinction.

As humanity picks up the pieces after the battle of Chicago, a shadowy group reveals itself in an attempt to control the direction of history…while an ancient, powerful new menace sets Earth in its crosshairs. With help from Cade Yeager, Optimus Prime and the Autobots rise to meet their most fearsome challenge yet.
In Transformers: Age of Extinction, consciousness is carried by machines — a plane of “metallic alien war”. The story fights on E9/E10 of the E0–E14 reality ladder, compressing prejudice, technology, militarism, exploitation.
