Not sure what all the hate is about with this game but I think it's because people are being conditioned to go with whatever social media are saying and this game was being hated on badly before it even came out... because I'm having a blast in Redfall. I'm 20 hours in and I'm loving the art style and atmosphere. When it gets dark it's properly dark and the cool blackned out sun looks especially good at times.
People who are having loads of problems must be playing it on a toaster or something because the only issues I'm having are some textures take a second to load in and there's a bit of clipping in some very small areas, they are literally the only problems I have and it's no big deal breaker nearly all games at launch have problems. Redfall runs very smoothly and is very playable in my experience with it. I use an XBSX with an LG c2 OLED 55'' to play and it's looks very nice overall with the art style of the game I didn't expect it to look as good with this art style but it does.
The AI aren't very good when there alone like mostly every other game ever made, but if you get caught out on your own against a group of enemies survival can be low unless you run away or hide behind cover, if it's a group of vampires you desturbed survival is even lower, 3 or more vampires at once is pretty much death as they will teleport to where ever you go..add a special vampire into this mix and there's very little hope unless you really make the most of the abilities that you will unlock as you progress through the game looking forward to playing more.
