Just off the top of my head... Zombies that are completely silent and sneak up on you like a ninja. Zombies that can track you like a heat seaking rocket. Zombies that can travel through walls. Hearing sounds like a Zombie scream when there is nothing around. Putting something on the ground only to have it dissappear. Constantly having to cancel actions because it glitches and does nothing. Controls that are complete garbage. Texture pop-ins when surveying areas. Falling through buildings. Glitching in lakes. The list goes on and on... One year of being a mod, 9 months in Alpha, and what you get from this group of devs is one of the most unplayable games ever made. You devs are pathetic and should be sued for purposely taking money when you knew you couldn't complete the task you were getting paid for. And brining this POS to PS4... lol I'd bet money it's another "Alpha" that never gets finished.
