I had a massive review but steam sent me back to my library and deleted it.

This is coming from someone who gathered EVERYTHING and upgraded before moving on to each next stage of the main story.

The weapons never become overpowered even with all the upgrades, they give you a leg up instead while keeping it balanced
The game sits on the edge of being too short but when you explore, solve puzzles, get upgrades and read lore, that time becomes decent so don't skimp out!
The game is its own experience (no its not bioshock, stop acting like its bioshocks sibling... its not)
the art direction and visuals are stunning and the soundscape is done amazingly well.
The music line up is fantastic and keeps you moving
I am running a 1080 SC and the game runs at max settings at a stable 120fps EASY
Boss fights are insane and keep you on your toes. They are quick and expressive and in my opinion HIGHLY enjoyably
I often found myself wanting to reload a save JUST to redo the fight.
melee weapons are hefty,brutal and I found them satisfying to use
The puzzles keep you thinking and entertained without running you down.
The abilities, while short and few; are useful and giving you the edge you need when fighting and I found myself using them A LOT.

OVERALL; Its worth the purchase and if you are concerned about the short story playtime then buy it on sale, Problem solved. However for what the game is and it being this developers FIRST major title.. it is VERY impressive! It is a semi-open world so expect glitches, we should know this by now. I for one didn't experience any real.. glitches that I can think of aside from getting locked behind a door but I had just saved so I just loaded the save point and it never happened again.
My only real issue I had with this game was the platforming. Your character has a bit of momentum when landing a jump so it can became quiet annoying after a bit but once you account for it, its smooth sailing.

I give this game 8/10
its worth playing, experiencing and enjoying. It might be short story wise but overall its a blast to play and I am happy with it.

I HIGHLY recommend you get this.
It can be a little grind-ish but its somehow just the right amount in my opinion.
The game itself is UNBELIEVABLY Laid out already, I thought this was the FINISHED GAME until I went and looked to remember its early access. There is so much content already and I am excited to see where it goes from here. There are areas that have yet to be completed build wise (of course you can't access them but you can see them on the map).

This is an early access game done PROPERLY. The combat is intense (especially for bosses), well thought out and weighty.
The Bosses are challenging if you haven't taken the time to grind and level. The abilities and weapons are dope, plenty of adjust ability for each encounter you will have. I had to back out of many fights and game plan what ability and weapons I should be using, what level I should be at and should I bring supplies. The game CAN be unforgiving, so be smart about who and when you fight.

Here are pros and cons from what I have experienced:

Pros:
amazing crafting system
Great building elements
Plenty of customization options for your "base"
Combat feels great
Bosses are challenging
Lots of ways to attack things/enemies
lots of negative environmental situations that make sure you rely on in game mechanics (like you are suppose to)
each boss has a Unique set of skills or abilities
and a lot of other things but I don't want to exactly spoil all of it.

Cons:
Server disconnect after 8 hours (honestly probably just AFK kick)

You have to AFK in order for timed task to complete, you cannot close the game if on PVE (I was playing PVE only to test the game at first before settling)

Bosses have a range of distance before they retreat the fight and heal ALMOST INSTANTLY, completely undoing all the damage you had done. You'll never know how far you can back up before they run back to their starting position either and they are INVINCIBLE the entire time they retreat! (The most annoying mechanic IMO)

NPC WEAPON SPAM (fire, bombs, explosions, ect)
This one is really bad, its like I traveled back to the black mesa days and got flogged by grenades.
Certain NPCs will spam wide spread attacks that when dealing with multiple NPCs, they are almost unavoidable.
Its that "eye twitching" level of annoyance with this one. You have been warned

Just a few things that need tuning, Otherwise the game is a must buy for me honestly. I haven't been this happy with a purchase in a while to the point that I am sad I have basically reached the end of whats available in game at the moment.
