Good Game the multiplier is great but the solo campaign is no let down noob or pro you'll love it
I also enjoy the multiplayer with it's wide range of game types and customization choices it'll allow your own load out that works best for you.
The new League plays is a great feature and I enjoy playing League matches it really makes me focus on my gameplay.
I've also found the new score-streak system to be good and well balanced making it so with enough practice anyone can get the high end scorestreaks.
Although i haven't personnel been able to use the new live streaming feature i have watched some of the people who have and it bring a great new interactive element to the game.
I've found Zombies to be fun and extremely enjoy able alone or with friends in transit or survival I always have a good time.
Overall I have found black ops2 to be a great game to play alone or with friends.
