When Cade and Savoy fight, it gets to the point where Cade gouges Savoy's eye and only stops when Savoy screams in pain and is slammed into the ground.
A man fried by a robot's grenade may scare younger kids.
Many scenes of intense robot action occur intermittently throughout the film. Explosions, shrapnel and carnage are frequent. The robots often "bleed" mechanical fluids. Some robots are shot in the head, or impaled by swords through the chest.
Early in the film one of the human 'good guys' is killed in a large explosion; there are several lingering shots of the charred remains of this body (still stood up, mid-run), coated in places with metal. Some camera angles show the body still on fire.
A human character late in the film is killed via a laser blast to the chest. A large burn mark is seen. Two men fight briefly and then a man throws another man out the window to his death. Another brief hand to hand combat between a women and two men. A guy from the elevator helps out.
