tl;dr Dead multiplayer, lack of tutorial, odd design choices, tedious gameplay.
I suppose an interesting concept and execution if it were original, or made instead as a mod for minecraft (I haven't played it, but there's got to be mods or something like this by now).
I liked the "atmosphere" and idea behind the game, but it's not very well done. The "combat" is somewhat clunky, though I've played worse. There's a smoke effect when objects are hit or struck by bullets that make it damn near impossible see what you're actually doing.The concept of scavenging by day and bracing yourself for attack by night are good ideas, but I'm pretty sure that's how Minecraft works (as I said earlier, I've never played the original). Also, zombies leap incredibly far and a single strike can take away a quarter health. If you can avoid being hit for about 3 seconds, you near instantly fully regenerate health.
There doesn't seem to be a set goal or anything to work towards (likely Minecraft's objectives, as well), so that left me experimenting with some game mechanics, all I was able to figure out was to move, shoot zombies on sight, and smack things with a pickaxe, allowing me to reposition the cubes I demolished with said pickaxe.
I wasn't expecting a AAA experience, but the little bit I've heard and the reviews I've read lead to an underwhelming experience on this game. Maybe I'm missing the best of the game, since I couldn't find a single server (not that I was really expecting a huge, dedicated playerbase). Single player might be good to run through it a couple times, but not much more. The game doesn't really make any sense and I don't suppose it's supposed to, but why zombies and dragons?
The best scenario I can imagine with this game is arming yourself to the teeth and trying to survive the night, but I haven't been able to figure out how to actually do this, as it's not worth spending the time in the game to gather the resources, craft the prerequisite items, gather more resources and craft the real items, to burn through everything in a matter of minutes.
In the vast majority of cases, I would not recommend this game to anyone as better alternatives exist and the money can be spent on them, instead. If someone with a few friends all own this title, or decide to all buy it at the same time AND can figure out the best scenario above, maybe a case can be made for this title. Otherwise, steer clear.
My experience was more or less "bumble about, exhaust ammo and weapons on zombies, die."
