Hoping there's both local and online co-op. Chief among these games is their masterful collection of co-op campaigns and modes. Wake me when you need me Wishlist.

Up to 4-player co-op (online, LAN, local, combo). You make spells from elements and accidentally or on purpose kill your friends. Such a magickal experience. Funny stuff after a few drinks local.

Up to 2-player online co-op. I myself am dead tired of zombies and didn't play it for long, but if you enjoy the idea of a zombie sandbox where you can endlessly mow the rising horde down, enjoy!

Up to 4-player local co-op. Let me preface with saying Sundered is one of the worst and prettiest games I've ever played. It has it's fans and it might be fun in co-op, so it's worth a mention.

I didn't find a dinosaur role-playing server in the sequel. I guess they went extinct. A bad game, but trolling with friends might make it a co-op experience. Life is what you make of it. ROAR!

It isn't a co-op game, but I found a dinosaur role-playing server. People we're primarily roaring carnage into their mics and writing dinosaur poems. Bad game. Good story though.

Up to 5-player LAN or online co-op. You shoot dinosaurs in a sci-fi setting. It wasn't good, but it definitely surpassed my expectations. Too much pride and preludice is bad for you.

Up to 4-player local or online co-op. It's a top-down heist/stealth game. Payday 2 ruined it for me, but it has quite a few fans so it's enjoyment might be Yours. Get Monaco-opping!

Online co-op. It's mediocre I fear, but it's free and it makes you cry tears of joy because it's pretty bad on today's standards. As fun as it is bad. Grab a few friends and waste away.

Up to 4 player online combo co-op (2 players per system) or 2-player local co-op. The game is cheesy bio-hazardous garbage that takes itself too seriously. That makes it hilarious for co-op.
