Wet 2 was in development when it was announced last November.n It looks like the game is no longer being made according to Siliconera.
A LinkedIn profile of a former Behaviour Interactive employee noted previously that the game was canceled. Another LinkedIn profile shows that the game is a past project.
Joystiq was also told by Bethesuda that the company is no longer publishing the game. This further suggests that Wet has all but evaporated.
