A teenage girl is seen bathing, we see her bare back and legs. Not sexual.

Soldiers fight using guns and knives. There is splattered blood when people are killed, but the acts are not directly shown. Instead we just see blood droplets and the victims as silhouettes.

There is a giant shadowy creature that rolls on the ground amid hundreds of people and make people's heads explode on contact, but it is shown as silhouettes so not particularly graphic or shocking.
