Call of Duty: Black Ops 4 will feature the biggest map ever made in Call of Duty history.
After the update Operation: Grand Heist (released February 2019), loot boxes were added into the game. Furthermore, skins which granted exp boots per kill meant Activision had lied regarding all micro-transactions being cosmetic only and about the fact that loot boxes would not be in the game whatsoever.
The Blackout mode follows the rules of well known battle royale games Fortnite and PUBG.
This will be the first Call of Duty game to not feature a single-player campaign
This is the first futuristic Call of Duty game not to include jetpacks.
