Seeing a lot of unintelligent reviews in either direction so let me elaborate on what most of these people are saying as a long time KF fan. All opinions here are aimed at the beta so if things change then I'll edit this review.

Let's start with the good.

Pros:  

Zed time feels great, it's honestly wonderful to have some actual feedback for when Zed time is going to pop off instead of it randomly happening. Helps reduce the amount of times you are 'Oops reloading during Zed time heehoo'. 

Guns feel and look great. This wasn't a surprise, TWI poured a ton of resources into the feel of guns for 2 so it only makes sense they did similarly here. They are responsive and neat, also love the addition of Ninja's Thrown weapons as a 'gun'. Needed more of that style of weapon in 2 

Zeds look raw and insane. They look truly horrifying and only get worse (in the good way) the more you stare. Having changes to how some of these enemies work was also refreshing and needed. (But some are better than others, we'll get to that in cons) 

Map layouts are interesting, and having more things to interact with and travel on is welcome. Having things like ziplines and ropes helps the levels feel less claustrophobic. 

Game overall looks great.......... BUT (cons) -Weapon customization was so needed and makes them feel varied and more special -Skill customization was ALSO very needed, again, makes me feel like I can be somewhat unique past just picking an upgrade every 5 levels. Classes in 2 only had 25 combinations each due to this restriction but these classes seem like you could have thousands of different setups.

Cons

Did anyone actually ask for Killing Floor to become a hero based game? The best part about 2 was the emphasis on player expression. There was an entire community shop in a similar vein to TF2 in terms of cosmetics, where you could trade with other players or straight up buy items from each other. Passed that you could then put most of the cosmetics on whoever you wanted to, and then take your favorite slightly mentally insane but now well dressed agent into a game and pick whatever class you wanted. The characters even had voice lines that pertained to each of the classes KF2 had to offer. Seeing that they decided to stick with this 'Specialist' system was a heart breaker... just means no variations in who we play. If a lobby wants to run all commandos they have to all be foster and that feels... wrong. It feels, dare I say, lazy.

I don't even really like the personalities of the specialists themselves. Remember when the internet had a tantrum over the incredibly obnoxious personality that was Frey from Forespoken? The 'Erm, so THAT just happened' type of personality? That's Devlin, the firebug. Next we have Foster who I could excuse not having KF2s VA since getting people to return for rolls can be hard, I get it, but the personality for him just isn't it. Hes somehow LESS cheeky than before. The rest keep following the trend of 'It just doesn't hit' and that's really a shame, because even if the lines were super reused, at least KF2s characters felt genuine and funny when quipping at Zeds or their teammates. Overall the designs aren't bad, just the sounds they make and how they make them, doesn't feel right.

I said that some changes to Zeds were welcome, here's the flip-side to that coin. Clots did not need a long ranged attack, especially since they gave bloats one too (longer than just melee range like KF2 anyway). They're supposed to be the filler, the meat to cut through to get to more annoying/troublesome enemies, not the annoyance themselves. They still do the forced turn when they grapple you which was all fine and well, but now we have to also get gunned down by them while dealing with everything else the game throws at you. Next up are the crawlers, they still retain their jump attack and now try to find alternative paths like on walls and ceilings which is very cool, but they also let them make ads (full transparency, citation needed because honestly i never witnessed it happen, just noticing the smaller ones appear from somewhere) or at the very least there are also smaller crawlers which means the ads have ads which is.... a choice. Sirens are cool looking but their scream went from being an attack that could surprise you given their smaller footprint among the rest of the zeds to being a very well telegraphed slow pseudo explosion that they barely ever get to do since melee just stuns them Indefinitely. They have a long wind-up before going off where as the KF2 sirens would just scream as soon as they knew they could connect damage. To cap off this part, weak enemies feel spongier and tough enemies like Skrakes and Flesh Pounds feel easier to kill which makes the game just feel odd. Killing clots in several swings of a melee and then killing a flesh pound in a few more hits and a charge melee doesn't feel right. Makes the big ticket enemies an annoyance instead of a problem.

A note on graphical fidelity. I'm sure that with a 50 series RTX card on full blast you could make all these settings look nice but the game looks better when you turn off global illumination and global reflections. Something about it just feels weird and also makes my 3070 want to die. The reflections especially have a weird 'comic book dot' effect when things are being reflected. Might just be the hardware I'm pushing but my specs are far from bad: Nvidia 3070, 64GB RAM, Ryzen 9 7950X, running on my M.2 drives. It's not a pushover PC which means this game is BEGGING you to have a new shiny graphics card to run smoothly. Tried to stream the game and went from 60fps to single digits randomly for seemingly no reason. Here's to hoping the beta just wasnt optimized.

The game has undergone what I wanna call 'CoDification'. What I mean is that the game looks less apocalyptic and more military, and the movement reflects it too. Specialists can only sprint forward, and they included a certified CoD slide which isnt in itself a bad thing, just feels wrong. I've been saying that a lot this review.

Conclusion
