a character gets raped offscreen. nothing is shown or heard

There is a gory decapitation, with promise of more to come. (Deleted. Personal opinions about ratings are not appropriate for the Parents Guide.)

Early in a woman is graphically shot twice in the chest, with blood spurting. First shot kills her, second shot is when she's already down. Gory.

Some fight scenes between aliens and humans (moderate violence).

Some mild exclamations.

Although there are some violent scenes which show some blood, these scenes are not that frightening because of the really bad CGI of the aliens.

The aliens look more stupid than scary.
