A slave is ordered to be sacrificed and is thrown from a height. His dead body is shown from a distance but there is no blood.
Mostly mild action violence, people getting hit in the head with clubs, stabbed and cut with spears etc. Nothing very graphic, though a few exceptions.
For one the main character stabs a giant bird in the mouth with a spear, no blood but just stabbing something in that area is quite violent.
One of the cavemen warriors run a soldier through with his spear, there is a bit of blood on the spear.
The main character throws a spear at a king, which hits him and he rolls down the pyramid steps. Some blood is on his white clothing and mouth.
