Octodad: Dadliest Catch will support local co-op for up to four players, developer Young Horses confirmed with Polygon today.

The game's co-op mode was revealed during our Polygon Live stream earlier this afternoon, where we showed off two-player co-op. Young Horses president Phil Tibitoski told us local co-op will work for two to four players, with each controlling one set of limbs. Players can drop in and drop out anytime from the game's menu and the mode will be present in the Mac, Linux, Windows PC and PlayStation 4 versions of Octodad.

Tibitoski also said the game features a four-player Roulette mode. In this mode, every time an objective is completed, the limbs each player controls will be randomly switched without indicating who is controlling what. For example, a player using the right leg could suddenly be controlling the left arm, and players will need to figure out for themselves who is controlling what. This mode can be toggled on and off.

According to the developers, co-op mode was added in around six months ago.

"We were talking about doing [co-op] for the longest time, and were trying to figure out whether Dadliest Catch would make players use one or two arms," Tibitoski explained. "We couldn't find a good way for one person to control both arms or a good reason for it, so it just kind of came from there. We tried it out and were like, hey, why not?

"The point of the game is obviously to master those controls, but I don't think they're necessarily difficult once you get past the first tutorial portion," he added. "People think it's difficult, but they will surprise themselves."

Tibitoski said there won't be online co-op for Octodad, and while Young Horses did briefly consider an eight-player co-op mode, it won't be an option. The game will launch tomorrow for Mac, Linux and Windows PC and for PS4 in March.
