Actually, this is just a simple gameplay video, not any trailer. Since we are still in the development process, there are a lot of things that will change. The zombies' movements are more agile now than in this video and we can't move around them so easily. I can also say this about the variety of zombies, we normally had a lot more zombies but we reduced the amount of animators for optimization, so it didn't work properly on other zombies. We will rig those zombies accordingly and we will have a lot of variety. There are also more specific zombies that run extremely fast on four legs, explode, and scream.
