Multiplayer: unbalanced matchmaking and special weapons. Obnoxious ttk. Movement is decent.
Zombies: 1/2 of the maps are unworthy remakes with terrible map design.The perk system is terrible. Special weapons, self revives, elixirs, and talisman are overpowered. IX is the only good map.
Blackout BR: understands what a BR game is, however I personally think that level 3 armor and ray guns in a battle royale game is overpowered. If it was free, it would be better.
Overall: fine graphics, terrible sound design, and money hungry game that forces you to spend money on supply drops. Possibly the worst Black Ops game. A ton of missed opportunities and wasted potential. 3/10
