Played for a couple of hours. In some ways its better than DayZ. Just picking things up, walking up stairs, ladders, etc. Inventory management is better. The best weapon I was able to get was a hammer. Although, it was rare that I got a gun in DayZ...unless I killed someone with an axe and took their stuff. And a couple times on a new spawns, I was sniped in under 1 min. I have never really had that happen in DayZ, only when approaching a city.
Zombies aren't too bright. Sometimes, though, they can one hit you. Other times they can take 10 hammer shots to the head. You can beat them easily by simply jumping on top of a car and cracking them in the head. I dont fear the zombies in WarZ, because if they get you its cheap. In DayZ you have to be more careful, because of the odd zombie behaviors, like glitching through things, weird rushing patterns, and general hit detection. Its cheap in DayZ too, but the randomness makes them scarier.
The real threat is the human players, like in DayZ, except its just about impossible to live for any length of time if there is a group patrolling around. I dont know where guns are...even at military installations, there are no guns. It maybe that this alpha map is too small, and they are just gone. I have heard and been killed by big caliber sniper rifles, M1014s and AK47s. If I could just find a pistol I would F these Bs up. At least with DayZ you can avoid people if you want, until you are armed enough to confront them. My longest life was probably 1.5 to 2 hours, and again, best weapon I had was a hammer.
Anyways, its not a total POS. Its basically like DayZ, plus and minus a few things. Its in alpha, so it has potential. It'll probably end up being which ever retail version is released first will own the survival zombie market. There isnt really any reason to own the both.
