From GameWatcher: “Publisher and developer Fatshark today offered new details regarding the state of Warhammer: Vermintide 2’s Season 2, which was initially intended to launch in December.
In a sense, Warhammer: Vermintide 2 players will still get Season 2 in December, albeit in the form of a beta test, as Fatshark seeks feedback on its implementation.”
