MUA3 only has 4 special move per character , this will have more atleast.Folks were shitting on Ultimate Alliance 3 for that? Damn. I know the footage isn't great and the game is still in early development so it's not finished, but it looks pretty... generic so far.
I wonder, is this the prologue? Because it's far from constant gameplay, lots of parts where it goes back into a cutscene it seems. There's no way it can play like that online. Imagine playing Destiny and it keeps taking you out of the gameplay. Has to be a intro mission of some sorts.
They may have not been shown in the press conferences, but there have been quite a few games that have had gameplay videos released later like Dying Light 2, Ghost Recon, Destroy All Humans, Gears 5, Control, etc.
What they show in the press conferences is up to them, and I think Microsoft really screwed the pooch in not having more gameplay demos.
