Imo, this game doesn't seem as good as it was hyped up to be. Looking at the gameplay, graphics are downgraded compared to modern warfare, and the parkour aspect of the game isn't as good. Meaning mounting is less limited and there aren't as many things you can jump over.
On the topics of guns they show how much the percentage of putting an attachment will affect your gun and they went down the path by making suppressors do less dmg, which is stupid, modern warfare doesn't do this.
The only hope I have for this game is their zombies and campaign at this point. Multiplayer doesn't really interest me to make me want to buy it, so I'm hoping if they have a "Warzone" it will be free.
