Black Ops 4 is back with 3 great games in 1: main game, zombies & battle royale. The main game uses "specialists" in team vs. team battles. Similar to Rainbow Six: Siege operators, or Overwatch heroes, each Specialist has a unique ability and special weapon. Plenty of different game modes to quench your thirst for frantic & headrush gameplay. New Heist mode is cool, full of tense corner peeks, capturing, tactics and money. The zombie campaign is excellent. The maps are massive and well designed and the zombie storyline characters are fantastic and funny. Overall, beautiful graphics, fast smooth game engine, excellent slow-motion replays, great voice acting and lots of replay value.
