It’s fine if that’s your impression from the videos. It’s hard to judge how a FPS feels without playing it, but most previews have said the gunplay feels good and the mele is surprisingly better than other similar games, almost has a “souls” flow to it.
There’s a big difference in saying the game looks a bit stiff and saying “omg that game looks terrible, xbots ha ha”
As far as hit reactions go, these are big ass metal robots, they wouldn't react like humans would. That’s a low quality video above so you can’t see it but in a better video you can see they take realistic damage from the bullets.
To add a bit of context to the video, that was just a person out in the open world causing trouble. There’s a wanted system ala GTA and that video is the equivalent of a person getting 5 stars and just fukkin around. Most encounters don’t go that way
, and you are actually discouraged from starting big firefights like this. The actual story sections play out very differently.
