I personally think black ops 2 and 3 yeah I'd say black ops 2 and 3. I didn't really like the boss thing because I was a bit of a maniac after a while especially when the ones got higher because it took actually a lot effort to kill them but however yeah I'd say black ops 3 because they did obviously make a few changes and I like the fact that they continue to make differences but I feel like when it got to how clean it is, they were under.
