[PC] Free - Overcooked (Normally $16.99 USD) @ Epic Games

Overcooked is a chaotic couch co-op cooking game for one to four players. Working as a team, you and your fellow chefs must prepare, cook and serve up a variety of tasty orders before the baying customers storm out in a huff. Sharpen your knives and dust off your chef’s whites, there isn’t mushroom for error and the steaks are high in these crazy kitchens!

Have this game and can vouch for it being awesome for two or more couch co-op.
