This is the game I have most hours of any in my library and through it's development in all throughout its early access years the game has improved in some aspects but deteriorated in many, the word optimization for developers has become cutting off features and changing good mechanics of game that made many players support this game and have others to join. There are many concerns as mentioned by many in reviews of the game but for me the biggest concert right now is "new"(in quotes because this mechanic has been implemented more than a year ago and still devs decline to revert it) puppet/zombie spawning system which spawns zombies randomly even after clearing off an area devs say they did this for optimization, sure but now you have no use of rifles as zombies only spawn close and feels very forced than organic like it was before.
The new horde system and zombies jumping through doors and windows is very nice but they again spawn randomly in there even if you cleared those buildings.
Before you would just clear off a town, village and loot it but now you cleared a police station walk to steps away from where you just killed a zombie and voila there's another one at same spot. This game even though it's many shortcomings still had that immersions for people to keep coming back to it but now the core part of it that is zombies are totally messed up. Hence I wouldn't recommend anyone to get the game in it's current state or unless zombies are reverted.

Admins kill you on Official servers, is it okay? I had a situation where, after killing a player in the B4 bunker, I was moving back to my car with the loot. I had parked it far away and was already moving through the forest when a drone showed up and sniped me in the bushes. This is definitely an act of revenge. Is this allowed on official servers? There was no cargo drops near by.

Game sucks, don't buy! Oh and Jagex&Gamepires/CroTeam, my wood is still bigger than the paid 2 inches...

Would not recommend, stay away until release or play Infinity Nicki for better customization for the same amount of Money.
I own this game since the first and original "2 inches" supporter pack mid 2018 and it has been "in development" since then.

What has changed? Or first, what has not changed:
UE4, the game has been in development for so long, they managed to outdevelop the UE devs by a whole generation, gfx are mediocre by modern standards so is gameplay, netcode and the "puppet"/zombie AI is just bad. The weird tincan mechs have never been updated, still sound/look worse than 2000 Deus Ex Mechs and feel like a pathetic puzzle difficulty increase for high tier loot zones with no actual plan on how to make them properly difficult...

What ACTUALLY has changed?
They did add a bunch of things, then ruined them again like vehicles... Or broken vehicles, or glitched out everything because broken vehicle. A bit of a tune down (just adjusting numbers/factors/variables in code) in terms of needing 20kg of any vitamin a day compared to 2020ish state of game. More more or less uneccesary guns, a copy/paste asset clone mechanically slightly more challenging bunker thing... Development is a joke.
Random ♥♥♥♥ like more guns, map extension... you name it, they added it but the gameplay/goals/loop have never received an update. Fighting a "puppet" (their iteration of a Zombie) feels like playing World war Z 0o no Infestation the new Z oh wait I think they changed name again game: 2 steps back, poke the wooden spear, 2 steps back, poke the wooden spear... rinse and repeat and if you are a half decent gamer you can punch em to death too.

And last but not least, the game did change. Development seems halted, bugfixing seems halted, anticheat seems halted but what they didn't stop doing is releasing 3d asset and texture/material DLCs for the better of 100$ by now for all the hair/character customization packs.

This game is dead and will most likely never release, the engine is aged into infinity, UE5 is out for 2 years soon and they are still "developing" on a 2014 game engine, 10 years old. All recent changes and releases have been related to selling literal assets for money with minor or no change to the game itself.

Any game that releases cosmetics before a 1.00.00.000.00000 version should receive an immediate pull and refund by Valve.

hate me for it or let it be known, this game stayed the same with minor additions and changes for 7 years while selling cosmetics instead of a release, it should be taken down
