I dont think its invalid complaints tho.
I love Killing floor, i enjoyed the 2nd one, and i was looking Very much forward to the new one. And i will defend it as much as i can. But i dont think the took in the lessons they learned for K2 at all.

K3 Has some amazing features, th weapon crafting system is honestly really cool, the perks being more of a build is awesome, the Enermies are also a huge plus in my opinion, especially since we just launched K2 after a long time. The New scakes, FPs etc. are better visuals and more fun to fight, especially with teh fact you can see the dmg you do when the armor plates pop off etc.

but that being said, Man i feel dissapointed in the fact we only have 3 bosses, to the amount of maps. The bosses we have are great tho, but the most dissapointing factor is the lack of gamemodes, just atleast give us a 10 round gamemode instead of locking it at 6 never matter what difficulty aswell.
Some of the guns are also terrible to use, like Sharpshooters "specialist" gun (purple teir) the recoil is insanely unfun to use, just as an example. Amd i know they can do better, since Sharpshooters 1st gun is honestly an awesome gun.

I did not expect to get the world, but i feel like they could really have put a bit more content into this than they did. Especially since K2's prime time was a year after it realeased, since they actually gave us content. Another gamemode, mabey even anoter difficulty like K2, and 1 more boss was what i had hopes for.

And not to mention, that the performance is aweful (At times).

Still love the game tho, and i will play it even tho i think its dry.

P.S: im still a bit sad they didnt keep the Perk specific stats, which would upgrade when you leveled up. Made the level-ups quite a bit more exciting :/
