Sorry for the mild necro, just wanted to report back now that I've gotten the game and the new patch has come out.
It's a mix between a horror game and a building/minecraft style game. You build a fort, defend it with traps/yourself and then sleep or attack the mutants forts/caves/whatever. You need to eat and stay warm/dry, as well as gather up a lot of materials for more complex crafting.
My initial thoughts after an hour or so's play:
-The combat is ok, and the fact that the mutants actively flank you is pretty impressive.
-It's scary enough, the graphics look fantastic and the weather/day/night system is great.
-There's quite a bit to explore and see, and the crafting (while basic) is good. However after a while you realize you're in a pretty bland forest with little except the mutant camps to break stuff up. It's good, just not really a sprawling open world.
-Crafting, whilst good, is a bit basic at the moment, there needs to be a significant amount more stuff in, and some of it can be tedious (carrying tree trunks about for instance).
It's worth a buy, although it might be worth waiting till patch 0.3 which should stamp out a few more of the bugs and add in some more needed content. I'm currently unsure where they can go with it - as fun as it is, it feels as though it might just end up that they add a lot of weird and wonderful weapons/crafting stuff, and it just become another crafting game with a few mutants around ala creepers in minecraft.
Anyone elses thoughts?
