I know the whole Smart Scope controversy is old news.
However, I would like to give my thoughts on it.
What do I mean when I say “Smart Scope controversy”? I mean this: The fact that Smart Scope looks like Aim Down Sights (ADS): A mechanic that is popular in games like Call of Duty.
Do I, personally, think Smart Scope is ADS? Yes and no.
Yes, there is a difference between Smart Scope and ADS. Though both do increase your accuracy, if you get shot while in Smart Scope you de-scope. This is not the case with ADS.
Here is why people say “Smart Scope is ADS” though: Both Smart Scope and ADS involve the player bringing the gun up to their eyes in order to look down the sight.
Aiming in Halo 5 is the same as aiming in previous Halo games, except for one thing: The aiming animation. In every previous Halo game, aiming was instantaneous: You clicked the right thumbstick, and instantaneously you were looking through the scope of, for example, your Pistol or Sniper Rifle. In Halo 5, you press the left trigger and it takes half a second for you to bring the gun up to your eyes in order to look down the sight.* In this sense — in the sense that the aiming animation is different, and as a result it takes you longer to aim in Halo 5 than it did in previous Halo games — contrary to what Frank O’Connor says in the Halo 5 multiplayer beta vidoc, Smart Scope has not existed since day one: Watch 3:36 — 3:58 of this video:
Now, what I’m going to say next is my opinion:
343 changed the aiming animation in Halo 5 to make it look like ADS, in order to appeal to Call of Duty fans and fans of other modern first-person shooters.
*Since the Halo 5 beta, the time it takes to aim has been decreased, but aiming is no longer instantaneous like it was in previous Halo games.
