Broforce (GOG Link)
Broforce is a side-scrolling platform shooter that seizes the shark, jumps it, then punches it in the face. Up to four players can participate in Bro-Op as they take on the roles of iconic action hero characters with over-the-top abilities and spectacular weapons as they combat terrorism and aliens. Together, they will shoot, jump, shoot, die, shoot, and high five their way through intense and challenging levels, then once again high five their pals when they get to the chopper. Did we mention that this game was MADE for high fives? Without local co-op, you couldn't high five your buddy, which would simply be criminal; however, if you want to be a rebel, Broforce offers online co-op as well.
Lovers in a Dangerous Spacetime (GOG Link)
Lovers in a Dangerous Spacetime is one of the few couch co-op games we can think of that understands a great co-op experience is as much about communicating and working together as it is about having fun when you fail. In this game, up for four players team up locally to pilot a circular spaceship with eight different stations. Coordinating the movement of a big floating orb while also figuring out where to position your shields and which enemies to shoot is not as easy as it first looks, and you're definitely going to have moments where you don't beat a level. That's okay, though, because you'll come close, all groan in mutual disappointment, rally together, come up with a new strategy, and then cheer as you win the day. It's a game for friends (and lovers) to enjoy together.
Never Alone (GOG Link)
Never Alone is a unique and touching puzzle platformer game where two players take on the roles of a young Iñupiaq girl named Nuna and her arctic fox companion. While the game does have some traditional elements of puzzle platformers (e.g. ranged combat, manipulating the environment to progress through the levels), the real strength of Never Alone is how the narrative is told and the game is structured. Presented as an oral tale based on a traditional Iñupiaq story, the game places videos between gameplay levels that contain information about the Iñupiaq people, culture, and storytelling traditions. While there are some rough edges at times regarding the gameplay mechanics, playing Never Alone is an experience well worth having. Traversing the snow-covered land as two small characters who are fighting against something that seems insurmountably large is an inspirational journey, especially with all the insight into the cultural background. Having a friend or a loved one by your side for this short, but supremely sweet, tale is something truly special.
