it was highly scripted and highly linear, but as people already said, I think they simply weren't ready to show more than this very "safe" kind of demo
if that's the general level design they go with for the majority of the game it would turn out pretty mediocre in comparison to other 3rd person cover shooters (not unsimilar to the Order), but it would be unfair at this point to assume so
btw I thought it was funny that massive storm just vanished the moment they closed the doors
