There's a lot of death and things exploding but I don't know if I'd say it was overly violent (but big war theme, obviously). But the alien and futuristic aspect take away a bit of the realism (of the violence). No sex and a bit of swearing but nothing much.
But obviously there is a bit of shooting at point blank range (to reboot) and if they get scared easily, it might be a little scary but I'd take a 10 year old...
