Plenty of action scenes throughout the show - shooting, punching, and explosions are all common. But it is almost never gory and when blood is shown it is never a lot.
Similar to it's predecessors, the series gets progressively darker and more violent. Stakes are raised and characters die more frequently.
Clones are tortured and experimented on by the empire.
The last episode of the series is easily the most violent of them all, and many characters die in the final battle. Some are impaled, some are shot multiple times. No blood is shown.
