A couple related issues that need some prompt attention (pretty game breaking from a combat standpoint).
1) Had the experience with both my weapons (AK-47 and Makarov) that single bullets I chambered from my inventory did zero damage; on my client, they would result in the shot appearing to be fired, complete with sound, but my buddies would only hear the click of the trigger. Only by piling my ammunition on the ground and chambering with RT would a bullet actually be fired. Nearly resulted in death on a few occasions from both zombies and other players.
2) Could not remove the magazine from my Makarov once it was in, so I was unable to load it, reload it, or use it other than chambering the aforementioned "magic" (re:useless) rounds unless I piled them on the ground.
A third issue not directly related is just the overall inventory experience. It is difficult with the controller to manage, the weight/carrying capacity numbers do not make any logical sense, and items can seemingly randomly be placed in other containers. I somehow put three items in my cooking pot already full of water, and then drank out of it.
Great potential here, and still had fun just trying to survive, but without a few of these things addressed in short order, the fun will die out quickly.
