Oddly enough, this trailer is one of the first clips from the Rogue One marketing campaign to directly reference the Death Star by name.
Not willing to accept certain death in the face of insurmountable odds, Jyn Erso yells at her fellow soldiers and demands to know what other choices they have besides hope.
Laying out its powers and its ability to destroy an entire planet, the rebels begin to lament the hopelessness of their cause.
As she speaks, we see gloriously violent shots of the rebels facing off against the technically superior Imperial forces, and it completely hammers home the idea that this rag tag group of rebels is in a last ditch fight for survival.
