Duck Game is no relation to Untitled Goose Game, unless you're in Minnesota.
SteamWorld Quest and Duck Game are going to be following each other quite closely in a few weeks.
Image & Form's card RPG SteamWorld Quest officially confirmed its April 25 release date today, following inadvertent reveals from both the North American and European branches of Nintendo. Quest will be a Switch exclusive "for the foreseeable future".
Duck Game, the long teased multiplayer game published by Adult Swim Games, will follow Quest on May 2. The four player game was the third of three games announced by Adult Swim before Switch's launch, along with Battle Chef Brigade and the recently released ToeJam & Earl: Back in the Groove.
