This is not for little kids under 18, this isn't a family game, this is Call of Duty World at War. Blood, gore, and guns
When I first started up the game, I spotted a new option in regards to watering down game detail, making it less violent, I mean I know this is a great feature in all, but if you're of age to play this, the option doesn't matter. But yes this game gets gory at times like the opening scene where you watch your comrade get his throat slit before your other comrades come in and kill your enemy. Kind odd on why they choose to start this mission off with that but whatever.
Online is like any other COD game, amazing, From more gun customization with multiple attachments not just the same ones for one class, and improved perks, Stopping power doesn't kill you like you are playing hardcore, as well, martyrdom has a smaller range to hit or kill people. The only thing I find annoying is the amount of places you can camp on maps and blind in. One minute you will be chasing an enemy down an ally way, next thing he is gone and pops out behind you. With Cage matches out there will be no more no more noobs cage matching for guns they can only use by spraying. BUT K/Ds are pretty much easy to increase, if you play free for all, as long as you maintain a +3 or more K/D during the game, you should get around a 30 – 10 or less score at the end of the game, if you play well. On the other hand though, with team matches like Domination, Headquarters, and TeamDeath Match, you will usually get a 24-14 score or less, because of all the kill stealers, which does give you the possibility to get a higher amount of kills, but a more higher chance of playing bad and dropping your K/D by a lot. The chances of dying, getting angry, and your K/D decreasing would be increased the more you play Team matches against hordes of enemy teams that only play COD 5.
Overall the guns are gun to use, no CAMO or Gold guns are kind of crappy as well, team matches like domination and sabotage have become more boring, while TeamDeath match has became very fun to play from COD 4's version of it. Story mode is fun, just boring at points, more of an online game, but worth maybe 40-50 dollars not 60-70+.
P.S. next year will have 2 Call of Dutys which is going to be annoying. Future and WW2, I just hope Infinity stays with modern or comes out with a modern patch.
