Are there any PS4 players here? If so and you like open world games and zombies you will like this. The shooting and stealth mechanics are solid, the open world isn't so big that you spend endless amounts of time getting from A to B, and the zombie hordes are great fun to take out and outwit.
I have been playing this on PC and it's great. If RDR2 is a 10 then I would give this an 8 (I skip many of the cutscenes).
During the night there are more zombies to deal with and during the day there are more people that will set up ambushes. On long trips I have to stop somewhere to get more gas. I was filling up 1 time and about halfway through a group of people jumped me. I have also been clotheslined off the motorcycle by a wire they put across the road. There also some animals and zombie versions of animals.
While exploring I'm constantly picking up stuff to make things (molotovs = rags + bottles + kerosene).
It is kind of like playing as Daryl from the Walking Dead.
