I got all achievements a week ago.
- Campaign was pretty good, much better than recent future campaigns
- Zombies is eh. BlackOps and IW zombies were better. BO4 is probably gonna blow it out of the water
- Multiplayer was fun until I discovered that shotguns are distinguished mentally-challenged broken (like holy shit broken), and one shot body to the sniper is still in this game
- Headquarters is crazy good, shits on Destiny's Tower
