I would not mind if the show real gameplay for the Campaign, as well as options that we will have throughout the game... and Gunsmith is part of it.
I want to see if we are able to mount a suppressor or a weapon at will or we are doomed if we did not choose it at loadout. I also want to see if we can change from single shot to burst to full auto on the fly or if we are capped with what we brought at loadout.
I want to see whether we will have a wheel to choose options or if key buttons for options... like press 4 to mount/unmount suppressor, 5 to throw a grenade, 6 to throw a smoke grenade, U to change fire mode, etc, etc.
I want to see a good portion of Enemy and Teammate AI behavior when not playing co-op and hopefully not a GCI scene of a take-down.
