Don't give this to your kids.
I was going to write a mock review. But whatever. I really only used to come onto sites like this to laugh at what people say about games but I need to be honest here.
THERE IS LOTS OF VIOLENCE AND GUNS. There is swearing. There is violent death and executions and blood. There is a dog who rips people's throat out who you get to control. There are almost no female characters so if you're hoping for a well balanced with good female role models, you'll be dissapointed. The multiplayer, while letting you play as a woman is a glorified gambling machine, it looks ugly, the color pallette is ugly. The multiplayer is so frustrating, your kid will probably start swearing, and then, you'll probably get older kids, teens and tweens and thirty year olds swearing and saying inappropriate things for anyone less than twelve.
The game also comes off as somewhat racist and the story is boring and bland and poorly written. I'd even recommend Black Ops III over this trash, because at least that game, while gratuitous with it's violence and swearing, has interesting ideas and themes baked into it, though definitely not for anyone under 16, even with the graphic content filter turned on.
And one last thing, the gameplay isn't even very good and it doesn't even have good music. If you're going to let a kid younger than 13 play this, play it with them, even if you just sit and watch and talk about it, you don't even have to touch a controller. There's this whole stigma about video games leading to violence with no substantial evidence, but children still shouldn't be exposed to certain things when they are too young. Yet if you still believe that they are linked, then don't let violent games raise your kid, don't buy it for them because you're too lazy to spend time with them or can't get them to find an off-screen interest.
This game is violent and not appropriate for kids, but worse than that, it's not even good.
