"Killing Floor 2 is chaotic fun. It’s messy, fast, gorgeous, frantic, and entertaining. All of the classes have their strengths, none of the weapons feel underdone or like they underperform, the details are carefully observed, and with the exception of the very rare bug or two, everything is polished to a mirror’s shine. Players who enjoy PvE shooters will probably find something to love out of Killing Floor 2, assuming they don’t mind the repetition."
Taylor Hidalgo, however, finds "it probably won’t convert players that were unconvinced by the first."
