In a new interview with Forbes, Activision has confirmed that the Call of Duty: Modern Warfare Remastered’s gameplay will remain the same as the original Call of Duty 4 title from 2007, but will feature graphic updates and more.
Meanwhile, the game itself will remain true to the original in terms of gameplay, guns, killstreaks and so forth. Maps and modes will remain unchanged mechanically, even while the game itself will look remarkably better.
This also seems to imply the same perks which was a hot topic when the game was first leaked.
With that being said, the weapons, kill streaks, modes, and more will be the same as the original Call of Duty 4: Modern Warfare title.
