For Mewgenics, there's a full-fledged co-op, actually, made by the fans themselves.
The mode allows you to go through one adventure together: players have a common map, cats, gold, stores and battles, and the management of the squad is shared between the participants.
Formally, the mode is designed for two, but technically, it's ready for three or even four players.
And the funny thing is, Claude wrote all the code, and according to the author, he didn't write a single line.
You're gonna need a free porthole and the mode itself to launch.
