Black Ops 2 is the epitome of the golden era of Call of Duty; probably the best CoD ever made. Unfortunately, they are still charging full price ($60) for this game from 2012. The multiplayer is full of security vulnerabilities and hackers. Even though the game is great, the price is completely ridiculous and as such you should only get the game on a sale. If you want to play multiplayer I highly recommend using the Plutonium modded launcher which fixes the security issues and has an anticheat.

i wish that theyd bring back mob of the dead again

This game will always have a special spot in my heart. I've loved the campaign since I played it for the first time in 2012 on the PS3. 12 years later i still come back and play the campaign over from time to time. I cant tell you if its the nastalgia, the story, or the characters that keep me coming back, but at least once a year i go through and play it through one more time. I dont think ill ever get sick of this or the first game for as long as ill live. It truely is PEAK Call of Duty, and no one can ever change my mind. 10/10 would recommend.
