Vermintide takes place in and around Ubersreik, a city overrun by Skaven. You will assume the role of one of five heroes, each featuring different play-styles, abilities, gear and personality. Working cooperatively, you must use their individual attributes to survive an apocalyptic invasion from the hordes of relentless rat-men, known as the Skaven.
