Excellent Single and Multiplayer, Offline and Online Experiences, will keep you hooked for days on end !!! Masterpiece !
Multiplayer is where this game shines. Like COD 4, there are many levels to go up ( about 70 in total). It is really addictive to complete challenges, increase your level and play matches and matches online. Apart from around two maps you will enjoy the map selection a lot. They are varied and each offer their own possibilities. You can create your own class and unlock new weapons. The multiplayer will keep you hooked for more than 50 hours + and is a blast. Offline multiplayer is fun too and can be played with 4 players on one console. I had great times with my friends so far.
Graphic is good, not comparable to works such as Mirrors Edge, Bioshock or Far Cry 2 but still really good. Otherwise there is nothing to complain about. This game can be played coop offline with 2 players, online with 4 players.
The Achievements are good, though you should be able to beat the game on Veteran if you want more than 300 points.
Bonus- Theres a mode, which is also playable offline coop and online coop called Nazi Zombies. Your aim is to keep Nazi zombies out of the house you are hiding in by closing windows with boards and upgrading your weapons as you reach kill streaks. Really fun and only adds to the perfection of this game!
GET THIS GAME!!!! IT IS PERFECT!!!! MASTERPIECE
