Very fun game. You get to build anywhere you want that is outdoors, which is awesome.
I wish there where more written notes and diaries that actually tell you something. I've done 4 play throughs and searched everywhere and everything and have only found 1 note that tells you the codes to all the vending machines. That's it. :(
Overall thoughts on the game as it's still in Alpha. 7/10.
(Combat) 5/10, it's pretty fun, but will get boring after a while. It's still a challenge though at the start.
(Crafting) 7/10 It basic, It's easy. You can craft on the spot without needing a workbench, and even build large structures.
(Building) 8/10 It's easy and fun. You can freely build anywhere you want, except indoors if it's a wall or barricade. The rotating is slow and you can only rotate one way. So if you mess up your angle, you'll need to restart.
You get resources back after taking something down you've built, which is good.
(Cooking) 5/10 You get quite a few different cooking options for the food you've gathered. Some foods need to be prepared by crafting them with some water so it can be cooked in a fire or stove. You cannot plant and farm anything in the game, so most of the food you will find are packets of oatmeal, rice, tea, instant coffee, etc.
Instant coffee is one of the best things you can find. It will recover your Body temp, fatigue, and thirst all in one when crafted and boiled into a Hot cup of coffee.
(Monsters) 4/10 Even though they are hard to kill when outnumbered, there are only 3 types. 1 fast, 1 normal, 1 slow.
Jackjumpers = Fast/Normal strength
Ghouls = Normal/ Normal strength
Peircers = Slow/Very Strong, Critical hits.
The most monsters I've seen in one place was 2 piercers, 4 jackjumpers, and 3 ghoul things. You don't see many of them though, and only a few. :P
After you are equipped with a decent weapon, some armor, and good defense and fighting skills, it's easy and sometimes so boring you just end up throwing grenades around for fun because you've already blasted all the other monsters.
But don't get me wrong, at the start of the game they are very difficult to fight.
