Killing Floor 3: Everything we know so far

Killing Floor 3 is a co-op horde shooter where you create a squad of six to mow down hordes of mutants known as Zeds. In our Killing Floor 3 preview, we were pleased with the game’s exhilarating and chaotic gunplay. You will also get to choose from various Nightfall Specialists, each having unique perks and skills that make their playstyle different from each other.

Moreover, the gunplay has been enhanced, with all shooting animations like gun recoil and reloading feeling smooth and punchy. The game is made bloodier now, thanks to its M.E.A.T. Gore System that adds more dismemberments and bloody spectacles. There is a healthy variety of Zeds in this game to keep you entertained for hours, with its striking visuals making the entire experience better and bloodier than before.
