I played it a bit, but frankly it is way to buggy at this point.
Me and my friends have only died from stairs and resets. Every third server you join will wipe your character clean upon spawning. Lots of items don't work and hacking is prominent. Item spawn doesn't work currently either as the servers have to do that manually by restarting the servers. The zombies are far weaker, very rare and can't run at all. I almost had to buy a second copy at one point because of the common no-clipping. I ended up in the backroom of a church with no way in or out. You can't respawn characters in SA, and none of my teammates could kill me. My character was trapped with no possibility of release. You can't even discard a character once logged out from the server. My two options where to buy a second license and thus a new character or contact rocket and try to make him respawn me. Luckily cheats still work so that character could be saved. I am aware that it is an alpha, but it is not even close to the state the dayz mod was in when it was in alpha. Once they have fixed:
Fix rampant hacking and cheating
Add item spawn
Make zombies common
Make zombies faster and into any sort of threat whatsoever
Fix stairs
Fix the join server/wipe character bug
Fix the clipping through walls, both with players and zombies
Fixed the greyed out respawn button which alleviates some problems in case of bugs
Add possibility to build camps, buildings, cars etc
Add quests
Once all of the above have been done have they managed to make it equal to the current state of the mod. I'd stick to Dayz Epoch until they have at least managed reach it in terms of features. In order to get people to switch over, they need to provide something which the mod doesn't and as it stands, it appears they are at least a year away from even coming close to the mod. I wonder what he did during the entire year the project was delayed to send it that far behind the mod.
