A drone is ordered to kill somebody; this thankfully ends up being prevented. Other characters are specifically threatened/planned to be killed.
Drones are shown threatening to kill people quite a few times with lasers pointed at their heads, or exploding things nearby and creating damage and falling debris.
There's plenty of people getting punched and shot at. Some people are shot but there's barely any blood.
There is a lot of physical damage to buildings etc., falling debris, people possibly falling to their deaths or being crushed by falling structures. An entire small town is shown as destroyed. There is mention of people being collateral damage.
