In addition, several online retailers, including Amazon, Gamefly and CD Universe also claim that the action romp has been picked up by the Fallout 3 crew. However, there seems to be some disagreement on when the game will arrive at retail. According to Amazon, Wet will ship on August 31, while both Gamefly and CD Universe expect the game to arrive on September 30 and 31 respectively.
Whatever the case, it seems probable that Wet has found a new home among the publisher's traditionally RPG-heavy catalog. While still unofficial, we've reached out to Bethesda in hopes of toweling off any additional information.
