This is a game about the Cold War. (Red Flag right there) Now, I'd like to say. This is not the worst M game out there. Far from it! I'll make three points. My review, why I said it's for 15 year olds, and if it's beneficial.
1. This is a great game! The story is very entertaining; sure there are 30 minute cutscenes, but they feel short because they are fun and entertaining. The story was masterfully done and it's probably better than most movies you've watched.
I actually find it quite surprising that the game manages to provide a serious story about an American soldier defecting to the KGB, yet still manages to make me laugh harder than most comedy films.
The gameplay is probably the best in the series. Each enemy base you encounter is has multiple entrances, new weapons scattered about, destroyable buildings and vehicles, mounted guns, multiple ways to take down your enemies, etc. Remember though, this is a stealth game. But the stealth mechanics are better than ever, with camouflage, smoke grenades, suppressors (silencers) for your guns, the CQC to interrogate and take out your enemies, and more.
PS: The soundtrack is perfect too.
2. The game does have some blood, cussing alcohol, sex, bombs, a complex plot and mature themes.
But you can turn the blood off and skip the mature cutscenes exclusively. So it would solve most of the issues. But even if you didn't it wouldn't be that bad. There are mostly just teases and when they do start; they keep their clothes on (except for the male character's shirt) and it cuts off before anything too sexual happens. (They really just kiss) Also, if your kid is pretty smart they'll understand the story. Mine's 12 and he understood every minute of it.
3. The story is pretty fictional, but it can teach your kid quite a bit about The Cold War, Russia, the UN, war, soldier's roles, to be careful who they trust and to be loyal to what you think is right, and not just to follow your country or ruler blindly. (Not
so extremely to tell the kids to start a rebellion)
Other Concerns: If you have seems some of the female characters in this game and think that they look sexist. Don't worry this game treats females and males equally! (SPOILER TERRITORY) The two main female characters in this game kick the main male character's butt! In fact one of them was just showing off revealing body parts to get the male character to trust her so she can get something from him.
