A very good game to buy for Christmas

I'll try to answer through this message:

Unlike the original game, this call of duty is in a war set in the future with new generation of weapons and often robotic.
Through the solo, so we find a war in North Korea, then a war against terrorism, themes which ultimately resemble those of today.
Note the presence in the game of Kevin Spacey who adds a touch of Machiavellian that he knows particularly in the series House of cards.

The solo so: he is quite successful as it is longer than the previous, which is always nice. For a long time we had not had this much fun since it must be said, the previous games were not that great.
A few negative points should be noted:
- The parts of sometimes long loads
- A game a little too scripted

Like any call of duty, the game takes place mainly in the multiplayer. I have noticed the massive lack of cheaters who kill anyhow. The parties are significantly more balanced and particular phenomena can impact the future part (eg tsunami).
It will also be much harder to kill enemies because of the exoskeleton technology to jump higher and farther.
The multiplayer is very well built and achieved and you can fully enjoy.

Overall, the graphics are excellent with the new graphics engine, weapons are also very well modeled.

Regarding the price, I advise you to look at Amazon as it is significantly cheaper than commercially
I invite you to look before buying the configuration of your PC and to provide 60 GB of free space on your hard disk and have a fairly powerful PC to run it.
I did not notice any particular beugs as some say.

In conclusion, I advise you to buy Call of Duty FPS is excellent and will allow fans of this type of game to have fun!
